Abdominal Mass Research Articles

Fetal Ovarian Cyst-A Scoping Review of the Data from the Last 10 Years.

Abdominal cystic masses are diagnosed during the intrauterine period and have a relatively low incidence. Fetal ovarian cysts are the most common form diagnosed prenatally or immediately after birth. The pathophysiology of the development of these types of tumors is not fully elucidated, with ovarian hyperstimulation caused by maternal and placental hormones being the most accepted hypothesis. During intrauterine development, the diagnosis of fetal ovarian cysts is most often made accidentally during usual check-up ultrasounds corresponding to the first, second, and third trimesters of pregnancy. We conducted a scoping review with the aim to map the current knowledge regarding the treatment of fetal ovarian cysts diagnosed in the intrauterine period. Focusing on the articles published in the last 10 years in the specialized literature, we tried to identify a conceptualization regarding the surveillance and treatment of these anomalies.

Research progress of integrated traditional Chinese and Western medicine in the treatment of advanced gastric cancer.

Gastric cancer (GC) is a malignant tumor originating from the gastric epithelium, and its incidence and mortality rates rank third among all malignant tumors worldwide. It is also one of the most common cancers in China and is treated predominantly by Western medicine in clinical practice. However, with the advancements in medical technology and informatics, the values of traditional Chinese medicine (TCM) in preventing and treating GC and improving prognosis have increasingly been recognized. According to TCM, clinical manifestations of GC can be divided into Yege (dysphagia), regurgitation, stomach pain, and Zhengxia (abdominal mass). Due to the unbalanced distribution of health care resources in China, most GC patients already have progressive or advanced-stage disease at the first diagnosis. As a result, most GC patients have poor physical function, and surgery or chemotherapy alone will aggravate the impairment to the immune function and seriously affect the quality of life. In contrast, TCM therapies have shown promising efficacy in the management of these patients. Here we review the role of the integrated TCM and Western medicine in treating advanced GC.

Lateralized overgrowth as a guiding sign of abdominal neoplasms for pediatric orthopedic surgeons.

This study aims to increase the awareness of the association between lateralized overgrowth (LO) and abdominal tumor among the pediatric orthopedic community and to evaluate its incidence in our center. Between January 1997 and December 2021, a total of 166 patients with Wilms tumors and hepatoblastomas were retrospectively analyzed. Data including age, sex, initial clinical signs (hematuria, abdominal mass with or without general discomfort), type of asymmetric regional body overgrowth (isolated or in relation with any syndrome), and tumor stage at diagnosis were recorded. In addition, age at which asymmetric regional body overgrowth was described and age at the time of tumor diagnosis were noted. Of a total of 166 patients, 133 were diagnosed with Wilms tumors (nephroblastomas) and 33 were diagnosed with hepatoblastomas. In 94% of the cases, the initial clinical signs were an abdominal mass and/or hematuria. Overall, five (3%) patients presented with LO. Four patients with Wilms tumor presented it at the initial clinical examinations. In three of these cases (2.3%), we found it isolated and, in the remaining patient (0.75%), it was associated with Beckwith-Wiedemann spectrum. Only one patient affected from hepatoblastoma (3%) presented with an isolated LO at the time of tumor diagnosis. Our study results show an incidence of LO in relation to intra-abdominal tumors of 3%. The latest updates recommend genetic testing to identify subgroups with a higher risk for tumor development that are more likely to benefit from tumor protocol surveillance.

A case of rapid canine nephroblastoma presumed metastasis documented with advanced imaging

AbstractA 1.5‐year‐old, female, entire German shepherd dog was presented for evaluation of an abdominal mass. The dog had a 4‐month history of polydipsia, polyuria, diarrhoea, and weight loss despite polyphagia. Abdominal ultrasound confirmed a large abdominal mass suspected to be uterine in origin. An exploratory celiotomy revealed a 4.3 kg, 26 × 17 × 17 cm multinodular mass entirely encompassing the uterus, left ovary and left kidney. A combined ovariohysterectomy and left nephrectomy were undertaken. Histopathology confirmed stage ΙΙ renal nephroblastoma with favourable histology. Chemotherapy was declined and 86 days following surgery, significant abdominal metastases were identified on a computed tomography scan. The patient was euthanased 113 days after surgery due to progressive disease. This is the first report to display the rapid presumed metastasis of a canine nephroblastoma, without gross metastasis at initial surgical resection, through advanced imaging. This is also the first reported case of polyphagia despite weight loss as a presenting clinical sign.

JB Sharma's white cotton ball sign: A new laparoscopic sign in abdominopelvic tuberculosis.

Abdominopelvic tuberculosis (TB) is a variant of extrapulmonary TB causing significant morbidity, including infertility. Results of 87 cases of diagnostic laparoscopy in cases of abdominopelvic TB diagnosed on composite reference standard (CRS) for demonstration of new laparoscopic white cotton ball sign are presented. Mean age, parity and duration of infertility were 27.2 years, 0.21 and 3.1 years, respectively. Oligomenorrhoea and hypomenorrhea were seen in 35 (40.22%) and 32 (36.78%) cases, while infertility was seen in all 87 (100%) cases while abdominal mass was seen in 27 (31.03%) cases and pelvic mass in 37 (42.58%) cases. Positive acid fast bacilli on microscopy and culture of endometrial biopsy was seen in 3.34% and 6.89% cases while epithelioid granuloma was seen in 12.64% cases on endometrial biopsy and in 13.79% cases on peritoneal biopsy. Positive polymerase chain reaction was seen in all cases while definitive abdominal pelvic TB was seen in 35 (40.1%) cases and probable findings in 42 (48.27%) cases. A new laparoscopic white cotton ball sign (resembling a large white cotton ball) was observed in 5 (5.74%) cases and biopsy from 3 showed it to be epithelioid granulomas positive. Demonstration of a new white cotton ball sign on laparoscopy seems to be a useful finding in abdominal pelvic TB.

Combined exploratory laparotomy, transpsoas, and thoracic approach to resection of a giant spinal ganglioneuroma: illustrative case.

Ganglioneuromas are rare peripheral nervous system tumors of neural crest origin. Most are often asymptomatic and incidentally found, but large tumors can cause mass effect. Herein, the authors report a case of a giant ganglioneuroma that arose from the lumbar foramina into the retroperitoneal and thoracic cavities. A 62-year-old female presented with low back pain, left lower extremity swelling, and increased sensation of an abdominal mass. Surgical treatment options were reviewed with the patient and coordinated care was planned by surgical oncological specialists. The patient opted for multistage exploratory laparotomy for abdominal mobilization, diaphragm resection, and en bloc resection with neuromonitoring. After surgery, the patient experienced significant improvement in symptoms. A combined surgical exposure involving gastrointestinal, thoracic, and neurological surgeons can be important in the safe resection of ganglioneuromas that span multiple body cavities. Hence, a thorough preoperative assessment could help plan surgery accordingly.

Wandering, twisted spleen in a deerhound

AbstractA 14‐month‐old, entire, deerhound bitch experienced episodes of abdominal discomfort. During some episodes, the abnormally shaped spleen could be palpated in the dorsocaudal abdomen, rather than in its normal cranioventral location. Exploratory laparotomy revealed an enlarged spleen that was twisted on its long axis but not on its suspensory ligaments. The spleen was excised, and the dog made an uneventful recovery. To the best of our knowledge, this is the first report of a so‐called wandering spleen in a dog, a condition that has been described in humans, albeit rarely. This also is the first report of a twisted spleen in a dog. Veterinary practitioners should include these two possibilities (wandering spleen and twisted spleen) in their list of differential diagnoses when presented with a dog experiencing abdominal discomfort or with an abdominal mass.

Vertebral Hydatid Cyst: A Case Report

BACKGROUND: Hydatid disease is caused by the larval form of Echinococcus granulosus. The reported occurrence of bony hydatidosis is 0.5–3% of all the cases and 50% of them affect the spine. Nevertheless, lumbar vertebral involvement is extremely rare. The most common occurrence is the dorsal level. CASE REPORT: We present the case of a 32-year-old-military dog handler, who presented in 2018 to the urology department with an abdominal retroperitoneal mass. The MRI showed multilocular cystic lesions. The patient underwent surgery, and all of the cysts were removed. The anatomopathological evaluation concluded to hydatic cysts. He was briefly relieved from his symptoms. He was addressed to our department in 2020 suffering from lumbar-radicular pain and functional impotence of both lower limbs. MRI was performed showing multiple big cysts with inhomogeneous contents. CT scan showed destruction of the l5 vertebra. The patient underwent surgery. Initially, we performed through a posterior approach, an L4 to S1 laminectomy, posterior stabilization, and then total L5 corpectomy, anterior l4-s1 fusion through a xipho-pubic laparotomy after 2 months. Antihelminthic therapy was administrated. The patient’s symptoms completely disappeared. No signs of reoccurrence were noted at the 2-year follow-up. CONCLUSION: The primary extrahepatic cystic echinococcosis of bone is an extremely rare disease. Diagnosis can be long and difficult. It can lead to serious complications and should be highly considered in case of a cystic vertebral lesion in an endemic region. Spinal involvement is extremely rare but potentially curable with surgery and anthelmintic drug therapy.

Ovarian Squamous Cell Carcinoma Arising from Mature Cystic Teratoma: A Case Report

Mature cystic teratoma of the ovary (MCTO) is the most common ovarian germ cell tumor. Its malignant transformation is a rare complication that occurs in almost 2% of the MCTs. MCTO is benign and usually appears between 30 and 40 years of age, but patients with malignant ovarian MCT are 10–15 years older than those with benign MCT. The most common malignant transformation in MCTO is Squamous Cell Carcinoma (SCC) which is rarely diagnosed with pre-operative imaging. We report the case of a postmenopausal woman, presenting with severe abdominal pain and a large palpable mass in her abdomen. She was diagnosed postoperatively with SCC arising from MCTO which was confirmed histopathologically. The patient received postoperative chemotherapy and was well at 6-month follow-up after chemotherapy. MCTO is benign, but can rarely become malignant in older ages. So MCTO-arising SCC should be considered in elderly women with abdominal pain and mass, and also some other evident features such as large tumor diameter, elevated serum markers, and solid components in Magnetic resonance imaging (MRI).

Clinicopathological Study of Ovarian Germ Cell Tumours in Tertiary Care Hospital, Tamil Nadu, India: A cross-sectional Study

Introduction: Ovarian germ cell tumours are a heterogeneous group of neoplasms derived from primitive germ cells of the embryonic gonad, either directly or indirectly. They can be classified as benign and malignant, with slow and rapid growth and spread, respectively. Benign ovarian germ cell tumours are common, while malignant tumours are rare and account for about 2.6% of all ovarian malignancies. They are more common in the second and third decades of life and typically present with abdominal mass, pain, and elevated serum tumour markers, which aid in primary diagnosis and follow-up. Aim: To analyse the distribution of germ cell tumours in the ovary in relation to age, parity, mode of presentation, biochemical markers, histomorphological patterns, and immunohistochemical markers. Materials and Methods: This cross-sectional study was conducted at Department of Pathology, Sree Balaji Medical College, Hospital and Research Institute, Chromepet, Chennai, Tamil Nadu, India. The study involved 86 ovarian specimens, of which 25 were germ cell tumours. Complete clinical history, radiological findings, and pre-operative laboratory test values were recorded. The ovarian specimens were carefully examined for gross appearances, fixed in 10% neutral buffered formalin for 24-48 hours, and subjected to histopathological processing, routine and special staining, and immunohistochemical study after observing the different morphological patterns of the ovarian specimens received. Results: The age range of presentation was between 14 years and 58 years. Seventeen patients were parous (14 benign and 3 malignant), and eight (5 benign and 3 malignant) were nulliparous. Abdominal mass and abdominal pain were the most common modes of presentation. Out of 25 germ cell tumours, 19 were benign cystic mature teratomas, 2 were immature teratomas, 1 was a yolk sac tumour, 2 were dysgerminomas, and 1 was a carcinoid tumour, with 6 being malignant and 19 being benign tumours. Among the 6 malignant ovarian tumours, 5 cases had raised serum tumour markers {cancer antigen-125 (CA-125), Alpha-Fetoprotein (AFP)} pre-operatively, and the levels reduced and became normal after surgery. Among the 2 cases of immature teratoma, one was Grade-II and the other was Grade-III. For one case with mixed tumour components, CD-30 and α-fetoprotein immunohistochemical markers were performed, showing negative and positive results, respectively. Conclusion: Among the histopathological subtypes, benign cystic teratomas were the most common ovarian germ cell tumours in this study. Both benign and malignant tumours presented with abdominal pain and abdominal mass. Most of the tumours were diagnosed between the ages of 21 and 40 years. In this study, α-fetoprotein immunohistochemical marker s

Seasonal gonadal changes in adult male lizards of Liolaemus cuyanus (Iguania: Liolaemidae) from the Monte desert, Argentina

Male reproductive cycles in lizards can be continuous or seasonal depending on the environmental conditions and female availability. The aim of this study is to investigate whether adult males of the psammophilus lizard Liolaemus cuyanus present seasonal changes of reproductive traits throughout the reproductive cycle. In order to carry out this task, sampling of specimens (N = 27) was carried out monthly from October to March in Valle de Matagusanos, Ullúm, San Juan, Argentina (31°06′46.08′’ S, 68°38′03.84′’ W; altitude: 945 m), a semi-arid zone. The animals captured in different months were grouped based on reproductive criteria according to three relevant periods: pre-reproductive (PrR), reproductive (R) and post-reproductive (PsR). In order to identify and characterize these periods, several male reproductive traits were obtained, like morphometric parameters (body mass, snout-vent length, testes and abdominal fat body mass), tubular surface and estimation of the interstitial tissue coverage, combined with histological and cell seminiferous tubule observations (germ cells types, histological and ultrastructural details) and presence of sperm in the cauda epididymis. During the PrR period, which occurred during spring, well-developed testes with free tubular sperm cells were present, but these were less frequent than during the R period. On the other hand, luminal sperm cells were evident at the seminiferous tubules from the beginning of the R period, in conjunction with the maximum testes mass and seminiferous tubular surfaces. This was also coincident with a higher abundance of sperm cells in the cauda epididymal lumen. At the end of this period, the initial regression of the seminiferous epithelium was corroborated by organelle regression which was observed in the ultrastructure of spermatogenic cells. At the beginning of the PsR period, before autumn, a marked decrease in male reproductive traits above described was detected. Instead, an increase in abdominal fat body mass could be observed indicating the onset of the lethargy period. The results obtained suggest that this population of L. cuyanus has a seasonal reproductive cycle, with its reproductive activity occurring during the spring-summer months (PrR-R periods) and finishing in late summer (PsR).

A giant intra-abdominal right testicular seminoma in a bilateral undescended testicle: a case report

Cryptorchidism is the most common congenital malformation of the male genitourinary tract. An undescended testicle has a 10% chance of developing cancer, with an intra-abdominal testicle having the highest risk. We present a 24-year-old man with a history of bilateral cryptorchidism, complaining of lower abdominal mass for two months. An abdominal computed tomography scan showed an intra-abdominal mass lesion measuring 13 x 9 cm and displacing the bladder caudally. Exploratory laparotomy revealed a right intra-abdominal testicular tumor. A right orchiectomy and left orchidopexy was performed. Histopathological examination revealed a testicular seminoma. The patient was discharged without complications and was referred to the oncology department for chemotherapy and further management. Our findings support the early treatment and close monitoring of cases of cryptorchidism due to the risk of malignancy as well as the necessity of routine scrotal examinations in all males presenting with an abdominal mass.

Abdominal Mass Revealing a Right Ovarian Cyst in a 2-Year-Old Infant: A Case Report

Introduction: Ovarian cysts are rare pathologies in infants. They represent 1% to 2% of all abdominal tumors in children. Abdominal pain is the most frequent initial sign. Sometimes the discovery is fortuitous, revealed by an abdominal ultrasound. We report here the case of an ovarian cyst in an infant in order to clarify the diagnostic and therapeutic particularities. Patient and observation: 2-year-old infant, female, weighing 12 kg and with no particular pathological history, was admitted to our department for pain plus abdominal mass evolving for 2 months. The clinical examination had noted: a mass ranging from FID to hypogastrium, painless, of firm consistency, with regular contour, with a smooth and mobile surface in relation to the deep plane. The abdominal ultrasound performed had concluded to a mesenteric cyst. The treatment consisted of a monobloc total cystectomy with preservation of the healthy ovarian tissue by a transverse laparotomy under the umbilical. The postoperative course was simple; the histological study of the surgical specimen had concluded to a serous cystadenoma. Conclusion: Ovarian cysts are benign tumors in most cases. Abdominal pain is the most common initial symptom at any age. Sometimes they can be incidentally discovered by ultrasound. The preservation of healthy ovarian tissue in the rules of oncological surgery allows the preservation of subsequent fertility.

Abdominal Cocoon Syndrome (ACS) or Idiopathic Sclerosing Peritonitis: An Extremely Rare Cause of Intestinal Obstruction

Introduction: Abdominal cocoon syndrome is an extremely rare cause of intestinal obstruction in which loops of small bowel are encapsulated by a fibro-collagenous membrane. This condition is also known in the literature as sclerosing peritonitis, and in the majority of cases, it has no known cause. The majority of patients exhibit long-standing signs and symptoms of partial intestinal obstruction. Presentation of case: A 15-year-old female patient presented with complete intestinal obstruction with no known co-morbidity and no history of prior laparotomy. Intraoperatively, the entire small bowel was found to be encapsulated by a dense fibrous sac. The peritoneal sac was excised, followed by lysis of the inter-loop adhesions with appendicectomy done at the same time. Discussion: Most patients with abdominal cocoon syndrome present with features of recurrent acute or chronic small bowel obstruction secondary to kinking and/or compression of the intestines within the constricting cocoon. An abdominal mass may also be present due to an encapsulated cluster of dilated small bowel loops. Conclusions: Abdominal cocoon is a rare condition causing intestinal obstruction, and diagnosis requires a high index of suspicion because of the non-specific clinical picture. Contrast-enhanced CT-scan (CT) of the abdomen is a useful radiological tool to aid in preoperative diagnosis. Peritoneal sac excision and adhesiolysis is the treatment, and the outcome is usually satisfactory.

PS-C26-6: HYPERTENSION DUE TO HYDRONEPHROSIS SECONDARY TO IGG4-RELATED DISEASE

Background: Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition that is capable of affecting multiple organs. It can present as an inflammatory pseudotumor in various organs. Patients may present with normo- or hypertension (HT) and urinary tract obstruction (UTO). Hydronephrosis (HN) leads to HT by overloading vessels or activating the renin-angiotensin system. Case presentation: A 53-year-old man presented with a two week history of abdominal pain. At admission, his blood pressure (BP) was 208/112 mmHg. His physical examination was otherwise unremarkable. Laboratory data and imaging revealed post-renal azotemia. HN was identified due to a mass around the aorta causing bilateral ureteric compression. The right ureter was considered to be more recently compressed because the left kidney cortex was more extensively thinned compared to the right kidney, respectively. Insertion of a double J stent in the right ureter led to improve urinary output with an attendant reduction of weight of 7 kg. Renal function also improved substantially (serum creatinine 5.66 mg/dL at admission; 1.34 mg/dL post-stent insertion). Initial treatment included intravenous nicardipine, followed oral nifedipine and telmisartan. With the above interventions, HT normalized to 132/71 mmHg in nine days. Finally, only telmisartan was required to maintain normal BP upon discharge. Biopsies of a salivary gland, the lip, and a cervical lymph node were non-diagnostic. The abdominal mass was not biopsied. Urine cytology was negative for malignancy three times. Serum lactate dehydrogenase was within normal limits, whereas soluble interleukin-2 receptor was elevated at 1,730 U/mL. IgG4-RD was considered as the likely cause. In accordance with current international diagnostic criteria for IgG4-RD, there was: 1) no exclusion criteria, 2) elevated serum IgG4 level, 3) hypocomplementemia, and 4) circumferential soft tissue around the infrarenal aorta. Oral corticosteroid therapy was prescribed. At 40 days post-discharge, follow-up imaging showed a slight reduction in the size of the soft tissue mass. Hypocomplementemia also showed improvement. Conclusion: HT was induced by UTO secondary to suspected IgG4-RD. It is reported that HT due to IgG4-RD occur in over one third of cases. Pathophysiology of HT includes renal parenchymal disease and HN. Laboratory data at admission revealed that the plasma renin activity and plasma aldosterone concentration were normal. His BP was ameliorated after urinary output improved, despite using antihypertensive monotherapy. Thus, we suspected that volume overload due to UTO led to HT. We suggest that HN should be considered as a differential diagnosis for the cause of HT.

Ovarian plasmacytoma: a case report

Plasmacytomas are a rare spectrum of plasma cell neoplasms that are single localized tumours, lacking the clinical features of plasma cell myeloma with no radiographical evidence of additional plasma cell tumours. Two clinical variants of plasmacytomas can be distinguished: solitary plasmacytoma of bone and extramedullary (or extraosseous) plasmacytoma. The latter is rare, representing 1% of all plasma cell neoplasms, occurring most frequently in the upper airways. Ovarian localization is exceptional, with only a few cases being reported in the literature. We herein report a case of an ovarian extramedullary plasmacytoma occurring in a 56-year-old woman who consulted for abdominal pain and abdominal mass, while highlighting the main histological and immunohistochemical features of this rare malignancy, along with a thorough review of literature gathering all cases of ovarian plasmacytomas reported to date.

Hydatid Cyst of the Liver: About a Case at the Digestive and General Surgery Department of the University Hospital of Bouaké (Côte d’Ivoire)

Hydatid cyst of the liver (KHF) is a parasitic condition caused by the development of the larval form of the dog tapenia Echinococcus granulosus. In sub-Saharan Africa, few writings are interested in this pathology, which remains common and constitutes a public health problem in highly endemic countries [1] [2]. We report the observation of a 61-year-old hypertensive patient owner of a dog admitted for abdominal pain without abdominal mass. In whom ultrasound and computed tomography have made it possible to make the diagnosis of hydatid cyst of the liver (KHF). The patient underwent surgery. We performed an associated conservative treatment post-operative albendazole. The post-operative follow-up was simple. In our patient the evolution was good after a setback of more than 2 months. Through this observation and a review of the literature, we insist on the contribution of imaging in diagnosis and treatment, which is essentially surgical.

Robotic left hepatectomy for schwannoma

Background: Schwannoma is a mostly benign, indolent tumor of Schwann cells, peripheral nervous system glial cells, which can occur anywhere in the body. However, primary schwannomas within the hepatic parenchyma are very rare. A 53-year-old man with no significant history presented with several months of non-specific abdominal pain and was found to have an abdominal mass on ultrasound.

A Case of Tubular Carcinoid of the Appendix: A Rare Entity

Carcinoid tumours of the appendix are low-grade neoplasms with neuroendocrine differentiation. They are typically found incidentally during appendectomies. Tubular carcinoid is an extremely rare, distinct, and benign form of appendiceal carcinoid. Here, we present the case of a 32-year-old male who presented with an abdominal mass and pain radiating to the right iliac fossa. Appendectomy was performed, and the gross examination revealed a congested and exudate-covered appendix. Microscopic analysis showed small tubules infiltrating the appendix wall, along with evidence of acute appendicitis. Differential diagnoses considered included carcinoid tumour with glandular differentiation and metastatic adenocarcinoma. Additional sections were examined, and a final diagnosis of tubular carcinoid was made after conducting a panel of immunohistochemical markers and Alcian blue stain. Since most tubular carcinoids are not identifiable on gross, microscopic assessment and serial sectioning play a crucial role in diagnosing this condition.
