Radio-Histopathological Spectrum of Ovarian Specimens Following Cystectomy

Ovarian cysts can be benign or malignant and requires accurate diagnosis for efficient treatment. Objective: To characterize the radiological and histopathological spectrum of ovarian specimens following cystectomy. Methods: This retrospective study was conducted at Pakistan Atomic Energy Commission General Hospital, Islamabad from 1st April 2022 to 31st December 2022.Eighty patient’s samples from cystectomy patients who were suffering from ovarian cysts were included. Each patient underwent radiological examination before ovarian cystectomy through laparoscopic surgery except two cases of urgent laparotomy. Gross histopathological specimen examination was conducted. The data were analysed using SPSS version 26.0, wherein p value <. 0.05 was considered as significant. Results: The mean age of the patients enrolled in this study was 35.5±5.9 years. Hemorrhagic cysts were having a reticular pattern of internal echoes with soli appearing area with concave margins and no internal flow, while endometrioma cysts were having homogenous low level internal echoes with non-solid component and tiny echogenic foci in the walls. While within the neoplastic cysts 4/8 werehaving cystic external surface and 1/8 presented with ovarian mass.The surface epithelial tumor presented of 2 cases with carcinoma detection on histopathology slides while in the germ cell tumor 1 cases each of strumaovarii, dysgerminoma and mixed germ cell tumor was observed. Conclusions: Surface epithelial tumors were the most common category of ovarian tumors and majority of the cysts were benign cystadenomas. Radiological imaging provides a precise non-invasive tool for categorizing various ovarian cysts and histopathological findings further confirms the exact category of tumors.

Mucinous cystadenoma and carcinoid tumor arising from an ovarian mature cystic teratoma in a 60 year-old patient: a case report

BackgroundMature cystic teratomas (MCT) of the ovary are benign ovarian germ cell neoplasms. Malignant transformation is possible but rare and ovarian carcinoid tumors in MCT are among the most extremely rare subtypes.Case presentationWe report a case of a 60-year-old Iranian woman suffering from postmenopausal bleeding and hypogastric pain for the last 40 days. An adnexal mass was detected during the physical examination. Ultrasound imaging showed a (55 × 58) mm mass in the left ovary. Total abdominal hysterectomy, bilateral salpingooophorectomy and comprehensive staging surgery were performed for the patient. Intraoperative frozen section of the left ovarian mass was indicative of a malignant tumor. She was diagnosed with a carcinoid tumor with benign mucinous cystadenoma arising on MCT of the ovary, confirmed in the histopathology and immunohistochemistry examination. The tumor was classified as low grade and no chemotherapy cycles were considered. The patient was followed up long-term and no recurrence was observed during 14 months of examinations.ConclusionOvarian carcinoids arising from MCT are rare neuroendocrine neoplasms, and proper diagnosis of these tumors requires careful histopathology evaluation and appropriate examination. Therefore, it is necessary to consider these tumors as a possible differential diagnosis and evaluate them in individuals (especially postmenopausal women) who have abdominal pain or abnormal bleeding and a palpable mass.

Discriminative diagnosis of ovarian endometriosis cysts and benign mucinous cystadenomas based on the ConvNeXt algorithm

PurposeThe objective of this study was to develop a deep learning model, using the ConvNeXt algorithm, that can effectively differentiate between ovarian endometriosis cysts (OEC) and benign mucinous cystadenomas (MC) by analyzing ultrasound images. The performance of the model in the diagnostic differentiation of these two conditions was also evaluated. MethodsA retrospective analysis was conducted on OEC and MC patients who had sought medical attention at the Fourth Affiliated Hospital of Harbin Medical University between August 2018 and May 2023. The diagnosis was established based on postoperative pathology or the characteristics of aspirated fluid guided by ultrasound, serving as the gold standard. Ultrasound images were collected and subjected to screening and preprocessing procedures. The data set was randomly divided into training, validation, and testing sets in a ratio of 5:3:2. Transfer learning was utilized to determine the initial weights of the ConvNeXt deep learning algorithm, which were further adjusted by retraining the algorithm using the training and validation ultrasound images to establish a new deep learning model. The weights that yielded the highest accuracy were selected to evaluate the diagnostic performance of the model using the validation set. Receiver operating characteristic (ROC) curves were generated, and the area under the curve (AUC) was calculated. Additionally, sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, and odds ratio were calculated. Decision curve analysis (DCA) curves were plotted. Results: The study included 786 ultrasound images from 184 patients diagnosed with either OEC or MC. The deep learning model achieved an AUC of 0.90 (95 % CI: 0.85–0.95) in accurately distinguishing between the two conditions, with a sensitivity of 90 % (95 % CI: 84 %-95 %), specificity of 90 % (95 % CI: 77 %-97 %), a positive predictive value of 96 % (95 % CI: 91 %-99 %), a negative predictive value of 77 % (95 % CI: 63 %-88 %), a positive likelihood ratio of 9.27 (95 % CI: 3.65–23.56), and a negative likelihood ratio of 0.11 (95 % CI: 0.06–0.19). The DCA curve demonstrated the practical clinical utility of the model. ConclusionsThe deep learning model developed using the ConvNeXt algorithm exhibits high accuracy (90 %) in distinguishing between OEC and MC. This model demonstrates excellent diagnostic performance and clinical utility, providing a novel approach for the clinical differentiation of these two conditions.

Diagnostic Accuracy of Frozen Section Analysis and Factors Associated with Discordance of Final Histopathology in Mucinous Ovarian Tumor

Aim and Objective This article determines the diagnostic accuracy of frozen section (FS) in case of mucinous ovarian tumor (MOT) and tailoring of intraoperative treatment decision. Material and Methods This was an observational study in which retrospective data was analyzed prospectively from January 2008 to December 2015 at the Regional Cancer Center. This study included 158 patients with MOT who underwent FS analysis during staging laparotomy at our institute. FS's sensitivity, specificity, and diagnostic accuracy were calculated and compared with final paraffin histopathological examination (HPE). Univariate and multivariate analyses were done to decide factors associated with changes in final HPE. Results FS analysis and final HPE report were concordant in 77.8% (123/158) of the cases and discordant in 22.1% (35/158). Out of 35 discordant cases, 29 (18.3%) were upgraded and 06 (5.6%) were downgraded. Out of 33 borderline cases, 16 (48.4%) were upgraded to malignant MOT and 6 (18.1%) were downgraded to benign MOT on final HPE. Out of 40 malignant MOT, 40 (100%) showed malignancy on final HPE. In the case of benign MOT on FS, 13 out of 85 (15.2%) upgraded to borderline or malignant. Sensitivity and specificity of FS were 76.60 and 55.17%, respectively, for benign MOT, 55.17 and 86.96% for borderline MOT, and 86.96 and 100% for malignant MOT. Conclusion In MOT, due to its large size and heterogeneous nature, it displays spectrum of appearance ranging from benign cyst adenoma, and borderline tumor to adenocarcinoma. Our study showed significant discordance between FS and final histopathological diagnosis in borderline MOT.

Mucinous cystadenoma of both ovaries and appendix: a case report

Epithelial neoplasm of ovaries is common and almost 40% of them are benign. Cystadenoma of ovary is the commonest epithelial neoplasm. They can be serous or mucinous. They arise from the surface epithelium of ovary, some of them may have germ cell origin. They are multilocular. 80% of ovarian mucinous cyst are benign cystadenoma. They are unilateral in 95% of cases. In this case presentation, it was bilateral and appendix was also showing mucinous cystic degeneration. The mucinous cystadenoma of the appendix is the most common mucinous cyst of the appendix, but the definite diagnosis is made at the time of surgical intervention only. The confirmation is reached by histopathology examination of specimen. This interesting case report is that of a giant bilateral ovarian mucinous cystadenoma of ovary along with the cystic degeneration of appendix. This is a rare case presentation scenario where bilateral giant cyst is found along with same pathology in appendix.

Correlation between plasma PSGL-1 and FIGO stage, tumor metastasis, and survival in epithelial ovarian cancer.

Plasma circulating P-selectin glycoprotein ligand-1 (PSGL-1) levels and its clinical correlation in patients with epithelial ovarian cancer (EOC) are unknown. The study determined plasma PSGL-1 levels in EOC patients and investigated its relationship with clinicopathological factors and prognosis. Plasma PSGL-1 levels were measured using ELISA in 69 patients with EOC, 34 patients with benign ovarian cystadenoma, and 36 healthy controls. Subsequently, the relationship between PSGL-1 levels and clinicopathological characteristics of patients, as well as the prognosis of EOC patients, was examined. Additionally, the specificity and sensitivity of plasma PSGL-1 were assessed through ROC curve analysis. Plasma PSGL-1 was upregulated in EOC patients compared with healthy subjects and/or patients with benign ovarian cystadenoma (p < 0.01). Elevated levels of PSGL-1 in the plasma were positively associated with advanced FIGO stage (p < 0.001), tumor size (p = 0.001), tumor metastasis (p = 0.036), and tumor recurrence (p = 0.013), while was negatively correlated with residual tumor size (p < 0.001). Kaplan-Meier survival analysis showed that high plasma PSGL-1 levels were associated with progression-free survival (p = 0.0345). In univariate and multivariate Cox regression analyses, PSGL-1 (HR = 1.456, p = 0.009) was an independent prognostic marker. Plasma PSGL-1 levels distinguished EOC patients and healthy individuals (AUC = 0.905), patients at late and early FIGO stages (AUC = 0.886), and metastatic and non-metastatic EOC (AUC = 0.722). The expression of plasma PSGL-1 is significantly increased in patients with EOC, serving as a reliable biomarker to differentiate between healthy individuals and those with EOC. Furthermore, PSGL-1 in patients is correlated with prognostic indicators, such as advanced FIGO stage, tumor lymph node metastasis, and progression-free survival.

Cistoadenoma mucinoso gigante de ovario

Although ovarian mucinous cystadenoma has a benign growth, it can grow to be very large. We present the case of a 70-year-old patient who came to the clinic for recurrent and diffuse abdominal pain. On physical examination, a large mass was palpated that occupied the entire abdominal cavity, up to the xiphoid appendix, rounded, retentive, with defined edges, non- painful, non-movable. Presence of edema in lower limbs. During the surgical act, a myomatous uterus and a giant left ovarian cyst measuring approximately 40 x3 0 cm and weighing 13.6 kg were identified. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. The biopsy confirmed the diagnosis of benign ovarian mucinous cystadenoma and uterine leiomyomatosis. The postoperative period progressed favorably. The incidence of giant ovarian cystadenoma is relatively unknown due to the lack of a standardized concept and currently available advanced imaging modalities.

Clinicopathological Analysis of Adnexal Masses Presenting in a Tertiary Healthcare Centre, Karnataka, India: A Retrospective Observational Study

Introduction: The ovaries, fallopian tubes, and the broad ligament make up the anatomical adnexa. Adnexal masses represent a commonly occurring issue in gynaecology. The majority of ovarian malignancies are detected at advanced stages. The clinical manifestations of adnexal masses vary, with many cancers either showing no symptoms or presenting with vague signs. In the reproductive age group, the most typical manifestation is a benign functional cyst. Aim: To conduct a clinico-pathological analysis of adnexal masses among women presenting at a tertiary healthcare centre. Materials and Methods: A retrospective observational study was conducted in the Department of Obstetrics and Gynaecology at Akash Institute of Medical Science and Research Centre, Devanahalli, Karnataka, India, from November 2022 to April 2024. The diagnosis of adnexal mass was based on clinical symptoms, abdominal examination, bimanual examination, and trans-abdominal ultrasound. The CA-125 and other tumour markers were sent depending on the risk of malignancy. All tissues were sent for histopathological examination. The data were collected and tabulated in a Microsoft excel sheet, and percentages were calculated. Results: This study included 38 cases, in which benign ovarian and para-ovarian cysts were the most common findings, observed in 21 cases (55.3%). There were six cases of benign serous cystadenoma (15.8%), three cases of teratoma (7.9%), two cases of high-grade serous carcinoma (5.3%), one case of germ cell tumour (2.6%), one case of mucinous cystadenoma (2.6%), two cases of endometriotic cysts (5.3%), one case of adnexal cystic degeneration of a fibroid (2.6%), and one rare case of primary fallopian tube carcinoma (2.6%). The most common presenting complaint was abdominal pain, reported in 21 cases (55.3%). Conclusion: Adnexal masses can present in a variety of forms, ranging from benign cysts to infections and cancers. A thorough history and clinical examination are essential for accurate diagnosis. Investigations support the diagnosis, and histology confirms it.

#292 : Combination of Hormone Replacement Therapy and Ovarian Stimulation as Endometrial Preparation Strategy for Refractory Thin Endometrium

Background and Aims: The aim of the case study is to demonstrate that combination of hormone replacement therapy with controlled ovarian stimulation is effective to improve endometrial thickness (ET) in difficult cases of thin endometrium. Method: The patient is a 35-year-old, nulliparous with primary subfertility for six years. She had PCOS with history of right salphingo-oophorectomy done for benign serous papillary cystadenoma. The male partner had severe oligoasthenoteratozoospermia. He started on FSH injections for three months with slight improvement in sperm parameters. She then underwent an IVF cycle and obtained five blastocysts. We struggled with thin ET with one failed frozen embryo transfer (FET) and two abandoned cycles. The patient was started with hormone replacement therapy on day one menses with tablet progynova 4 mg six hourly together with estrogel 3 g eight hourly transdermally. A scan was performed on day one menses and endometrial thickness was 4.5 mm. The serum progesterone and luteinizing hormone was baseline. A repeat scan for ET was done on day seven menses and was noted to be 6.4 mm. She was given another four days of oral and transdermal estrogen and the ET remained 6.4 mm at day eleven menses. We decided to perform low dose ovarian stimulation with recombinant FSH 150 IU daily. She was then seen on day fourteen menses for repeat scan. The ET only marginally increased to 6.7 mm. We increased the injection to 225 IU daily. On day eighteen menses, her ET was 7.8 mm and we triggered with HCG 5000 IU. She had her FET done on day twenty-five menses. Results: Her BHCG two weeks later was 948.3 U/L. The pregnancy is currently ongoing at 18 weeks. Conclusion: A combination of hormone replacement therapy and ovarian stimulation enables the exogenous and endogenous estrogen to act synchronously on the endometrium to achieve better endometrial thickness for implantation.

An enormous benign primary retroperitoneal mucinous cystadenoma: a case report and literature review of a seldom seen abdominal pathology.

Retroperitoneal neoplasia comprise less than 2% of all tumours. benign primary retroperitoneal mucinous cystadenoma (PRMC) is an extremely rare tumour. Their clinical course is overall silent unless the patient presents with a vague abdominal or pelvic pain, abdominal distention, or a palpable mass. Their aetiology remains theorized and since 1989, only 46 cases (excluding ours) worldwide were documented in the literature. The majority of cases were discovered in females but the overall tumour incidence rate is still undetermined due to its rarity. Well-timed recognition of this pathology permits the necessary curative surgical intervention to take place. We hereby illustrate the rare case of a 23-year-old female who presented to the surgical clinic complaining solely of an unexplained gradual increase of the abdominal contour. Their presurgical radiological analysis yielded an intraabdominal large-sized well-demarcated retroperitoneal mass. Thorough resection of the mass was accomplished via open surgery. The subsequent microscopic analysis of excised tumour yielded the diagnosis of primary retroperitoneal mucinous cystadenoma of benign nature. Primary retroperitoneal mucinous cystadenoma is a seldom seen tumour. The scarcity of its occurrence is further highlighted by the published data. Based on their conclusive review of the available published English-based literature, ours is the 47th documented case of a benign PRMC and it is the first documented case from our country; Syria. The impact of these findings warrants raising awareness on the subject and considering PRMC as a differential diagnosis when presented with a similar case in the clinical practice.

Blood Plasma Small Non-Coding RNAs as Diagnostic Molecules for the Progesterone-Receptor-Negative Phenotype of Serous Ovarian Tumors.

The expression level of the progesterone receptor (PGR) plays a crucial role in determining the biological characteristics of serous ovarian carcinoma. Low PGR expression is associated with chemoresistance and a poorer outcome. In this study, our objective was to explore the relationship between tumor progesterone receptor levels and RNA profiles (miRNAs, piwiRNAs, and mRNAs) to understand their biological characteristics and behavior. To achieve this, we employed next-generation sequencing of small non-coding RNAs, quantitative RT-PCR, and immunohistochemistry to analyze both FFPE and frozen tumor samples, as well as blood plasma from patients with benign cystadenoma (BSC), serous borderline tumor (SBT), low-grade serous ovarian carcinoma (LGSOC), and high-grade serous ovarian carcinoma (HGSOC). Our findings revealed significant upregulation of MMP7 and MUC16, along with downregulation of PGR, in LGSOC and HGSOC compared to BSC. We observed significant correlations of PGR expression levels in tumor tissue with the contents of miR-199a-5p, miR-214-3p, miR-424-3p, miR-424-5p, and miR-125b-5p, which potentially target MUC16, MMP7, and MMP9, as well as with the tissue content of miR-16-5p, miR-17-5p, miR-20a-5p, and miR-93-5p, which are associated with the epithelial-mesenchymal transition (EMT) of cells. The levels of EMT-associated miRNAs were significantly correlated with the content of hsa_piR_022437, hsa_piR_009295, hsa_piR_020813, hsa_piR_004307, and hsa_piR_019914 in tumor tissues. We developed two optimal logistic regression models using the quantitation of hsa_piR_020813, miR-16-5p, and hsa_piR_022437 or hsa_piR_004307, hsa_piR_019914, and miR-93-5p in the tumor tissue, which exhibited a significant ability to diagnose the PGR-negative tumor phenotype with 93% sensitivity. Of particular interest, the blood plasma levels of miR-16-5p and hsa_piR_022437 could be used to diagnose the PGR-negative tumor phenotype with 86% sensitivity even before surgery and chemotherapy. This knowledge can help in choosing the most effective treatment strategy for this aggressive type of ovarian cancer, such as neoadjuvant chemotherapy followed by cytoreduction in combination with hyperthermic intraperitoneal chemotherapy and targeted therapy, thus enhancing the treatment's effectiveness and the patient's longevity.

Intraoperative predictors of appendiceal abnormalities in patients with mucinous ovarian neoplasms.

To evaluate intraoperative factors predicting appendiceal pathology during gynecologic oncology surgery for suspected mucinous ovarian neoplasms. We conducted a retrospective study on 225 patients with mucinous ovarian neoplasms who underwent surgery for an adnexal mass with concurrent appendectomy between 2000 and 2018. Regression analyses were used to evaluate intraoperative factors, such as frozen section of the ovarian mass and surgeon's impression of the appendix in predicting appendiceal pathology. Most patients (77.8%) had a normal appendix on final pathology. Abnormal appendix cases (n = 26) included: metastasis from high-grade adenocarcinoma of the ovary (n = 1), neuroendocrine tumor of the appendix (n = 4), and low-grade appendiceal mucinous neoplasms (n = 26; 23 associated with a mucinous ovarian adenocarcinoma, 2 with a benign mucinous ovarian cystadenoma, and 1 with a borderline mucinous ovarian tumor). Combining normal intraoperative appearance of the appendix with benign or borderline frozen section yielded a negative predictive value of 85.1%, with 14.9% of patients being misclassified, and 6.0% having a neuroendocrine tumor or low-grade appendiceal neoplasm. Benign or borderline frozen section of an ovarian mucinous neoplasm and normal appearing appendix have limited predictive value for appendiceal pathology. Appendectomy with removal of the mesoappendix should be considered in all cases of mucinous ovarian neoplasm, regardless of intraoperative findings.

Over tümörlerinin ayırıcı tanısında sistemik inflamatuar belirteçlerin rolü

Aim: The aim of this study is evaluating the predictive value of preoperative inflammatory blood parameters for differential of serous cystadenoma, serous borderline ovarian tumor (BOT) and high-grade serous ovarian (HGSOC) carcinoma.&#x0D; Materials and Method: In this single-center study, we retrospectively enrolled 370 patients with ovarian tumors were divided into three groups. The groups were classified as serous cystadenoma, serous BOT and HGSOC. The potential association of preoperative hemoglobin (Hb), red cell distribution width (RDW), Hb/RDW ratio, ratio of neutrophils to lymphocytes (N/L) and ratio of platelets to lymphocytes (P/L) were analyzed.&#x0D; Results: P/L and N/L were significantly lower in benign serous cystadenoma or serous BOT than HGSOC (p

P-757 The classification and management of adnexal masses identified during pregnancy

Abstract Study question How do we classify adnexal masses (ovarian cysts) identified during pregnancy and how should we manage them? Summary answer Adnexal masses (ovarian cysts) should be managed expectantly in pregnancy, given the low rate of complications and low prevalence of malignancy. What is known already Conservative management of adnexal masses (ovarian cysts) is preferable during pregnancy, due to the maternal and fetal risks associated with surgery. Accurate diagnosis is key to safe expectant management. Various ultrasound-based models exist to classify adnexal masses; however, none have been validated for use in pregnancy. Adnexal mass morphology can change during pregnancy due to decidualisation, which is often difficult to distinguish from underlying neoplastic processes. We aim to evaluate:(1) the performance of current methods of adnexal mass classification in pregnancy, (2) understand the natural course of adnexal masses in pregnancy, particularly the presence of decidualisation and incidence of complications. Study design, size, duration Retrospective analysis of prospectively collected data between January 2017- November 2022. To classify adnexal masses (ovarian cysts), we evaluated: Expert subjective assessment (SA), IOTA Simple Rules (SR) and the IOTA Assessment of Different Neoplasias of the Adnexa (ADNEX) model. The end point was either the histological examination of tissue removed at surgery or the subjective classification of adnexal masses at the postnatal scan in women managed conservatively. Participants/materials, setting, methods Women with an adnexal mass identified on gynaecological ultrasound in pregnancy at a tertiary London University Hospital were included. Relevant clinical data was extracted, including age, gestation and cyst-related complications. Adnexal masses were classified at the first antenatal and postnatal ultrasound examination according to SA, SR and the ADNEX model (10% risk of malignancy cut off) and correlated to histology for adnexal masses managed surgically. IOTA simple descriptors were used to classify benign adnexal masses. Main results and the role of chance 254 women (median age 33-years old, range:18-49) with an adnexal mass/cyst were included at a median gestation of 12 weeks, (range:4-36). 13 (5.1%) conceived through assisted reproductive techniques. Spontaneous resolution occurred in 24.5% of cases, and 21 were lost to follow up (8.3%). According to Simple Descriptors, 38.6% were simple, 22.0% were endometriomas and 19.7% were dermoid cysts. Antenatally, SA outperformed ADNEX, based on specificity (94.6 vs.92.2%) and sensitivity (60 vs.55.6%) respectively. SA and ADNEX had a negative predictive value(NPV) of 96.1% and 98.3% respectively. Postnatally, SA had a higher sensitivity than ADNEX (75 vs.50%), but a lower specificity (94.1 vs.96.9%). SA and ADNEX had a NPV of 94.1% and 97.5% respectively. Three (1.3%) underwent acute surgery during pregnancy: one ovarian torsion (9/40), and two cyst ruptures (11/40, 30/40). Presumed decidualisation occurred in 29.5% of endometriomas. Three (1.3%) underwent cyst removal during caesarean section, two for suspicion of BOTs (one had suspected decidualisation) and one for patient preference. On histology, the suspected decidualised mass was a serous BOT, and the suspected BOT was a struma ovarii. In the postnatal period (12 weeks), four underwent surgery for suspicion of BOTs, two were confirmed BOTs and two were benign cystadenomas on histology. Limitations, reasons for caution The dataset as expected contains a relatively small number of malignancies (prevalence 3.9%) and so any analysis of test performance to discriminate between benign and malignant disease must be interpreted with caution. A larger prospective multicentre study is needed to do this. Wider implications of the findings Our data suggest that a number of cysts in pregnancy will resolve, a few will be associated with acute complications and the risk of malignancy is very low. Accordingly, the study supports an expectant management approach for adnexal masses (ovarian cysts) detected in pregnancy. Trial registration number Not applicable

Histopathologic Examination of Ovarian Lesions: A Prospective Observational Study in Women from Central India

Background: There is age related increase in the incidence of ovarian cancer. Most Indian population-based cancer registries have reported a gradual rise in the ovarian cancer incidence over the years. Since ovary is composed of totipotent gametocytes and multipotent mesenchymal tissues, almost any type of tumor can arise from these tissues. Therefore, their proper recognition and classification is important for appropriate therapy and better prognosis.Aim: to look at the histopathological profile of various ovarian lesions in the local female subjects from central India.Methods: A prospective observational study was carried out on the surgically resected ovarian samples that were referred to the Pathology department over two and half year. A total of 100 ovarian cases were included. Histopathological examination of the specimen was done using standard protocols.Results: On gross examination, majority of non-neoplastic specimen showed unremarkable findings. Microscopic examination of non-neoplastic cases revealed that most of the cases were of follicular cyst followed by corpus luteum cyst. On the contrary, majority of neoplastic specimen showed cystic external surface on gross examination. Surface epithelial tumor was the most common histologic type amongst neoplastic cases. Most common histologic subtype amongst the surface epithelial tumors was found to be benign simple serous cystadenoma. Conclusion: In women from central India, commonest non-neoplastic lesion of ovary is follicular cyst whereas most common neoplastic lesion is surface epithelial tumor (benign simple serous cystadenoma).

HISTOPATHOLOGICAL SPECTRUM OF OVARIAN TUMORS: A DESCRIPTIVE STUDY

Surface epithelial ovarian tumors was the most common category of ovarian tumors followed by germ cell tumors, sex cord stromal tumors and metastatic tumors in decreasing order of frequency. Incidence of benign tumors was much higher than malignant tumors with benign serous cystadenoma being the most common benign tumor and serous cystadenocarcinoma being the most common malignant tumor. Reproductive age group showed higher incidence of ovarian tumors whereas there was increasing incidence of malignancy with increasing age group. Exception to this was the higher incidence of malignant germ cell tumors in adolescent age group. Although nulliparity and low parity showed higher risk of malignancy, early menarche did not reveal any signicant increase in malignancy. Pain in abdomen was the most common symptom whereas ascites was more commonly seen with malignant tumors. Menstrual complaints were observed more commonly with tumors with functional stroma with possible role of hormonal inuence. Benign tumors showed cystic morphology and there was signicant increase in incidence of malignancy in tumors with complex or solid morphology. Thus age more than 50 years, post menopausal age group, solid and complex tumor morphology, presence of ascites, nulliparity or low parity and bilaterality of tumors signicant increased incidence of malignancy and thus these parameters can be used to predict the risk of malignancy in ovarian tumors. This was a descriptive study and analysis of data was done using chi square test and logistic regression analysis

Coexistence of a huge Brenner's tumour and mucinous cystadenoma in a 62-year-old female: a case report from Syria.

In this manuscript, the authors report a case of a 62-year-old nulliparous Syrian woman who presented with severe abdominal distension, which was followed by laparotomy and the excision of a 25×20cm-cyst; its pathological examination confirmed a benign Brenner's tumour and mucinous cystadenoma. Ovarian Brenner and mucinous are usually benign and can rarely grow asymptomatically to very big sizes. Herein, the authors aim to emphasize the importance of excluding malignancy by pathology examination. Walthard cell nests undergo metaplasia to give rise to different kinds of Brenner and mucinous neoplasm formations according to their genetic alterations. This paper adds to the available literature, which is still poor, by providing evidence of the first case of this rare combination from Syria with a review of different theories of origin and differential diagnoses. More studies directed towards exploring this combination's genetic origin are needed to boost our understanding of ovarian tumours in general.

Giant mucinous cystadenoma of the pancreas in a young female

Cystic tumors of the pancreas are rare and may be confused with hydatid cysts, especially in endemic areas. The incidence of cystic neoplasms of the pancreas is relatively rare in the pediatric population and young adults. We present a 21-year-old female with a well-defined giant multiloculated cystic lesion in the body and tail of the pancreas, which was diagnosed as a hydatid cyst elsewhere. The patient underwent laparoscopic spleen-preserving distal pancreatectomy. There was no visible communication between the mucinous cystic neoplasm and the pancreatic duct. Histopathology confirmed the diagnosis of benign mucinous cystadenoma of the pancreas. Ambiguity in the management of the lesion arises when mucinous cystadenoma is commonly misdiagnosed as pancreatic pseudocyst because the surgical management is entirely different.
