Клиническое наблюдение гипоталамического ожирения у ребенка с нейрофиброматозом I типа и глиомой хиазмально-селлярной области

Neurofibromatosis (NF) is a genetic disorder characterized by the development of various types of benign or malignant tumors affecting ether the central or the peripheral nervous systems and manifested also on the skin in the form of “café au lait” spots as well as other signs sometimes. Thus, this disorder requires multidisciplinary approach. The clinical case observed in the Article is no exception.: a patient with coffee-colored spots all over the body from an early age was described with similar familial symptoms in the patient’s father, two brothers. At the age of 4 months old, after the first DTaP vaccination, nystagmus appeared, after the second vaccination - progressive deterioration of vision, and at the age of 3 to 4 years old the hearing loss joined in. For the 6 years the patient was observed by pediatrician, ophthalmologist, otolaryngologist and neurologist and received courses of retrobulbar injections of vascular-metabolic drugs, hardware treatment and physiotherapy with slightly positive effect. The first MR imaging of the brain was performed at the age of 7 y/o when a glioma was detected in the chiasmatic-sellar region. Starting the age of 7 y/o the patient gradually developed and increased hypothalamic obesity with subsequent metabolic complications in the forms of impaired glucose tolerance, hyperinsulinism and insulin resistance, arterial hypertension and non-alcoholic fatty liver disease. At the age of 12 a heterozygous mutation in the NF1 gene (deletion of 4 nucleotides) in exon 5 was detected: c.495_498delTGTT:p.T165fs, which made it possible to establish a diagnosis of NF type 1. This case reflects the multifaceted nature of the disease, the importance of a multidisciplinary approach and its early diagnosis.

Prevalence of Neoplasms in Patients with Acromegaly-A Single-Center Polish Study.

Background/Objectives: Neoplasms are one of the three most common causes of death in patients with acromegaly. Our study aimed to assess the incidence of benign and malignant neoplasms among patients with acromegaly and the associations between this prevalence and the disease activity, the time of acromegaly diagnosis, and the time of its first symptoms. The correlation between neoplasm occurrence and pituitary somatotropic axis hormone levels was also studied, and the prevalence of different types of neoplasms was compared between the patients with acromegaly and the Polish population. Methods: A retrospective study included a statistical analysis of the medical documentation of 230 patients with acromegaly diagnosed and treated in the Department of Endocrinology, Diabetes, and Isotope Therapy in Wrocław (Poland) between 1976 and 2023. Results: We observed 171 cases of neoplasms (144 benign and 27 malignant). All types of neoplasms and benign tumors were diagnosed more frequently, in both the short and long term, after a diagnosis of acromegaly, but, after a long time, only malignant neoplasms were more frequently diagnosed. In the cases of controlled acromegaly, all types of neoplasms and benign neoplasms were more common than in cases of cured acromegaly. The incidence of neoplasms was higher, regardless of type, in patients with active acromegaly compared to the cured disease. Malignant neoplasms of the thyroid, renal, and stomach type were more common among our subjects compared to the Polish population. Conclusions: This study confirms the association between acromegaly, as well as its activity level and the time from its diagnosis, and the prevalence of neoplasms.

Clinical features and rehabilitation outcome after surgical treatment of spinal meningioma.

Retrospective analysis of clinical routine data. Spinal meningioma is a common type of benign spinal tumor. Surgical removal is the standard therapeutic approach. While surgery is generally associated with excellent outcomes, little is known about the rehabilitation outcome of patients with postoperative deficits. Therefore, we aim to describe the clinical features and rehabilitation outcomes of patients after surgical removal of spinal meningioma. Region of Swabia, Bavaria, Germany. We conducted a retrospective analysis of patients with spinal meningioma who underwent a rehabilitation program for patients with non-traumatic spinal cord injury at our department over the past five years. In addition to routine data, we focussed on analysing the Barthel Index, SCIM III score, and ASIA impairment scale before and after rehabilitation. 15 patients were included in the analysis. While most of them only had a few restrictions relevant to activities of daily living, some had severely limited walking ability. The predominant clinical feature was incomplete paraplegia with or without neurogenic bladder and bowel affection. The Barthel Index and SCIM III score demonstrated positive changes in the majority of cases, while alterations in the ASIA impairment scale were observed in a minority. Considering the results of outcome parameters, rehabilitation treatment appears effective for these patients. Nonetheless, further studies with larger patient cohorts are necessary to confirm these findings.

A Case of Single Surgical Removal of Two Distinct Meningiomas with Different World Health Organization Grades and Subtypes in an Elderly Patient

Meningioma is one of the most common types of benign primary brain tumors in older adults, and multiple meningiomas are reported in fewer than 1% to 10% of cases. However, there is no definitive treatment guideline for patients with multiple meningiomas. An 80-year-old man presented with abruptly impaired cognition and was found to have two distinct meningiomas located in the temporal and frontal lobes. A single frontotemporal craniotomy was performed to remove both tumors. Pathological analysis revealed different subtypes and World Health Organization grades for each mass. The patient showed symptomatic improvement, experienced no postoperative complications, and exhibited no signs of recurrence during a 1-year follow-up period with evaluations at 3-month intervals. Despite the absence of a standard treatment for multiple meningiomas, surgical resection in a single procedure is feasible in selected patients.

Retroperitoneal lymphangioma in a tertiary care hospital of North India

Less than 200 cases of retroperitoneal lymphangiomas (RL), a rare type of benign cystic tumour of the lymphatic system that makes about 1% of all lymphangiomas, have been documented to date. Their rarity makes preoperative diagnosis challenging. 95% of lymphangiomas are found in the head, neck, and axilla where they are most frequently found. We are presenting a 30 years old woman, who presented to outpatient department (OPD) of general surgery with symptoms of recurrent left lumbar pain, radiating towards inguinal region for one month. The contrast computed tomography (CT) scan of abdomen and pelvis defined a large thin walled homogenous non enhancing hypodense cystic lesion in left side of abdomen in retroperitoneal location from left lobe of liver till pelvis on left side craniocaudally. The patient was planned for exploratory laparotomy. Midline laparotomy was performed. A cystic lymph-filled tumour was detected in the abdominal cavity adjacent to the bowel loops. Histologically the mass contained variable-sized cystic spaces lined by flattened endothelium consistent with lymphatic vessels, which on immunostaining were positive for CD31 and negative for Pan CK. The patient was discharged satisfactorily. In conclusion, retroperitoneal lymphangioma presents vaguely as abdominal pain or mass and grown to large sizes without causing any significant symptom. Tumour markers for the excised tissue are important for diagnosis. Laparotomy or laparoscopy are the two surgical excision methods used to treat retroperitoneal cystic lymphangioma and it responds well to excision.

Artificial Intelligence (Neural Network) in the Diagnosis of Benign Skin Tumors in Pediatric Patients

Relevance: ten years ago, artificial intelligence (AI), particularly neural networks (NN), as a diagnostic option in practice seemed a distant prospect. Today, the use of AI is becoming an increasingly popular and daily improving approach in all aspects of clinical and fundamental medicine. Purpose: design and learning of a NN to recognize four types of benign melanocytic skin tumors, integration into a mobile app to apply in practice. Material and methods: сlinical and dermatoscopic analysis of skin tumors was carried out in 600 children. In 65 cases the tumors were removed. Histological types were dermal nevus – 43% (n=28), complex nevus - 33.8% (n=22), pyogenic granuloma - 10.8% (n=7), Spitz-nevus - 6.2% (n=4), blue nevus - 3.1% (n=2), melanoma - 3.1% (n=2). Seven patients with pyogenic granulomas and two patients with melanoma were excluded. The test set included 56 dermatoscopic images. Due to the small number of images augmentation was performed. The database has been increased from 600 images to 1800. NN is written in the machine language Python. The machine learning framework was TensorFlow 2.0. The network architecture is based on the pre-trained model “EfficientNet B7”. This model uses the “supervised learning” paradigm. Each element of the sample had a class affiliation. Results: an accuracy of 83% was achieved after a period of learning on the test set. Mathematical metrics calculated in the Scikit-learn library. Sensitivity was 100% (blue nevus), 73% (complex nevus), 93% (dermal nevus), 75% (Spitz-nevus), and specificity were 98%; 94%; 82%; 98%, respectively. AI was integrated into the mobile app “KIDS NEVI”. Conclusion: AI as an auxiliary method for the skin tumors diagnosis in children and adolescents has demonstrated high potential and great opportunities. Dermatoscopic analysis of a skin tumor and a mobile app are able to provide “double control”, quick and correct clinical diagnosis and determination treatment tactics.

Machine learning-assisted diagnosis of parotid tumor by using contrast-enhanced CT imaging features

PurposeThis study aims to develop a machine learning diagnostic model for parotid gland tumors based on preoperative contrast-enhanced CT imaging features to assist in clinical decision-making. Materials and methodsClinical data and contrast-enhanced CT images of 144 patients with parotid gland tumors from the Peking University School of Stomatology Hospital, collected from January 2019 to December 2022, were gathered. The 3D slicer software was utilized to accurately annotate the tumor regions, followed by exploring the correlation between multiple preoperative contrast-enhanced CT imaging features and the benign or malignant nature of the tumor, as well as the type of benign tumor. A prediction model was constructed using the k-nearest neighbors (KNN) algorithm. ResultsThrough feature selection, four key features—morphology, adjacent structure invasion, boundary, and suspicious cervical lymph node metastasis—were identified as crucial in preoperative discrimination between benign and malignant tumors. The KNN prediction model achieved an accuracy rate of 94.44 %. Additionally, six features including arterial phase CT value, age, delayed phase CT value, pre-contrast CT value, venous phase CT value, and gender, were also significant in the classification of benign tumors, with a KNN prediction model accuracy of 95.24 %. ConclusionThe machine learning model based on preoperative contrast-enhanced CT imaging features can effectively discriminate between benign and malignant parotid gland tumors and classify benign tumors, providing valuable reference information for clinicians.

SUCCESSFUL TREATMENT OF VON HIPPEL-LINDAU DISEASE-ASSOCIATED RETINAL CAPILLARY HEMANGIOBLASTOMA WITH BELZUTIFAN IN A PEDIATRIC PATIENT.

The authors describe a case of a retinal capillary hemangioblastoma (RCH) in a pediatric patient with von Hippel-Lindau (VHL) syndrome that was successfully treated with systemic belzutifan. The clinical course was documented with serial fundus examinations and multimodal imaging, including Optos widefield fundus photography and optical coherence tomography. A literature review was conducted to look for similar cases and/or discussion. A left RCH was noted on a standard VHL surveillance retinal examination of a then 15-year-old male patient with VHL syndrome. Over the course of 17 months, this RCH was treated with focal laser therapy, photodynamic therapy, cryotherapy, bevacizumab injection, and endolaser ablation. Complications of these treatments included subretinal fluid and vitreomacular traction necessitating laser retinopexy, scleral buckle, and pars plana vitrectomy with membrane stripping. After a 6-month interval from the last local therapy (endolaser treatment), there was minimal regression of the lesion, and many concerning features persisted. At 22 months from presentation, the patient started belzutifan 120 mg PO daily with subsequent regression in size and less perfusion to the hemangioblastoma within 4 months. The patient is tolerating the systemic belzutifan with only the expected normocytic anemia and has not required transfusion therapy after 12 months of treatment. von Hippel-Lindau disease is a rare and serious condition associated with multiple types of benign and malignant tumors. Belzutifan is tolerated in the adolescent population and can provide a systemic treatment alternative for VHL-associated RCH.

Lateral intraventricular epidermoid cyst: A case report

Background: Epidermoid cysts originate from ectopic embryonic epithelial cells and are a very common type of benign intracranial tumor. Epidermoid tumors located in the lateral ventricle are exceedingly rare. Case description: We present a rare case of a 55-year-old man complaining of a recurrent headache over a 2 year-period. A non-contrast CT scan and MRI of the head revealed a large mass within the right lateral ventricle. Gross total resection of the lesion was retained but unfortunately the patient refused surgery. The prognosis for patients who undergo surgery is excellent and depends on the quality of tumor removal.

Comparison of Peptidomes Extracted from Healthy Tissue and Tumor Tissue of the Parotid Glands and Saliva Samples.

Salivary gland tumors are highly variable in clinical presentation and histology. The World Health Organization (WHO) classifies 22 types of malignant and 11 types of benign tumors of the salivary glands. Diagnosis of salivary gland tumors is based on imaging (ultrasound, magnetic resonance imaging) and fine-needle aspiration biopsy, but the final diagnosis is based on histopathological examination of the removed tumor tissue. In this pilot study, we are testing a new approach to identifying peptide biomarkers in saliva that can be used to diagnose salivary gland tumors. The research material for the peptidomic studies was extracts from washings of neoplastic tissues and healthy tissues (control samples). At the same time, saliva samples from patients and healthy individuals were analyzed. The comparison of the peptidome composition of tissue extracts and saliva samples may allow the identification of potential peptide markers of salivary gland tumors in patients' saliva. The peptidome compositions extracted from 18 tumor and 18 healthy tissue samples, patients' saliva samples (11 samples), and healthy saliva samples (8 samples) were analyzed by LC-MS tandem mass spectrometry. A group of 109 peptides was identified that were present only in the tumor tissue extracts and in the patients' saliva samples. Some of the identified peptides were derived from proteins previously suggested as potential biomarkers of salivary gland tumors (ANXA1, BPIFA2, FGB, GAPDH, HSPB1, IGHG1, VIM) or tumors of other tissues or organs (SERPINA1, APOA2, CSTB, GSTP1, S100A8, S100A9, TPI1). Unfortunately, none of the identified peptides were present in all samples analyzed. This may be due to the high heterogeneity of this type of cancer. The surprising result was that extracts from tumor tissue did not contain peptides derived from salivary gland-specific proteins (STATH, SMR3B, HTN1, HTN3). These results could suggest that the developing tumor suppresses the production of proteins that are essential components of saliva.

Esophageal ganglioneuromatosis; a rare cause of intractable esophageal stenosis: a case report

BackgroundGanglioneuromatosis is a rare type of benign neurogenic tumor that usually affects the sites of the major sympathetic ganglia in the retroperitoneum and the posterior mediastinum. Affection of the gastrointestinal tract is rare, and involvement of the esophagus is exceptional. To the best of our knowledge, only 4 cases of esophageal ganglioneuromatosis in adults were reported in the literature. No cases have been reported in the pediatric age group.Case presentationAn 11-year-old boy presented with dysphagia due to severe esophageal stenosis caused by esophageal ganglioneuromatosis.ConclusionsDespite its rarity, the present case implies that ganglioneuromatosis should be considered in children with idiopathic esophageal stenosis.

Feasibility study of ResNet-50 in the distinction of intraoral neural tumors using histopathological images.

Neural tumors are difficult to distinguish based solely on cellularity and often require immunohistochemical staining to aid in identifying the cell lineage. This article investigates the potential of a Convolutional Neural Network for the histopathological classification of the three most prevalent benign neural tumor types: neurofibroma, perineurioma, and schwannoma. A model was developed, trained, and evaluated for classification using the ResNet-50 architecture, with a database of 30 whole-slide images stained in hematoxylin and eosin (106, 782 patches were generated from and divided among the training, validation, and testing subsets, with strategies to avoid data leakage). The model achieved an accuracy of 70% (64% normalized), and showed satisfactory results for differentiating two of the three classes, reaching approximately 97% and 77% as true positives for neurofibroma and schwannoma classes, respectively, and only 7% for perineurioma class. The AUROC curves for neurofibroma and schwannoma classes was 0.83%, and 0.74% for perineurioma. However, the specificity rate for the perineurioma class was greater (83%) than in the other two classes (neurofibroma with 61%, and schwannoma with 60%). This investigation demonstrated significant potential for proficient performance with a limitation regarding the perineurioma class (the limited feature variability observed contributed to a lower performance).

Significant results from a major multi-year, multi-cancer follow-up study with an enrollment of over 19,000 individuals.

10539 Background: Multi-cancer screening has become a major approach for early stage cancer screening and prevention. However, there has been very few reported multi-year, multi-cancer follow-up studies to validate the effectiveness of multi-cancer screening. We report a number of significant, major findings from what we believe the first large scale, multi-year, multi-cancer follow-up study. Methods: In this study, cancer differentiation analysis (CDA) technology, a bio-physics based detection platform, has been used to screen over 200,000 individuals in a general population. Based on the CDA test values, individuals have been classified into high risk, medium risk and low risk (for cancer) groups. Up to January 31, 2024, a total of 19,141 individuals have been enrolled, with 1,122 in high risk, 15,784 in medium risk, and 2,235 in low risk group. In this follow-up study, enrolled individuals were initially contacted within 6 months (high risk individuals were contacted within 15 days after the test report became available) and subsequently on an annual basis, and their health conditions were recorded. Results: Up to January 31, 2024, 256 individuals have been confirmed with cancer, 1,607 confirmed with pre-cancer diseases and benign tumors, and finally, 1,378 confirmed with diseases. When enrollment is normalized (number of individuals enrolled into each group is equal), for confirmed cancer group, 91.4% is in high risk group, 7.5% in medium risk group and only 1.1% in low risk group. The above result is very significant, indicating that multi-cancer screening using CDA technology is very effective. As shown, there are 23 types of cancer (Table). There are close to 30 types of pre-cancer diseases and benign tumors confirmed. Above results showed that CDA technology is indeed very effective in screening out multiple cancer types (including some cancer types which do not yet have other effective IVD tests such as thyroid cancer and esophageal cancer). The results also show that this approach is very helpful for cancer prevention as it screened out large number of pre-cancer diseases and benign tumor types. Conclusions: A large scale, multi-year, multi-cancer follow-up study has been carried out. Results showed that CDA technology is effective for multi-cancer screening in a general population.[Table: see text]

Schwannomas: Experience from a single center reference in Peru.

e14043 Background: Schwannomas are nerve sheath tumors that originate in Schwann cells. They are usually solitary and sporadic and manifest on peripheral, spinal or cranial nerves. It is the most common type of benign peripheral nerve tumor in adults. These tumors represent a diagnostic challenge due to their rarity and difficult differential diagnosis. Our objective was to determine the clinical and pathological characteristics, as well as the therapeutic management of patients with Schwannoma admitted to our institution over a period of time. Methods: A retrospective, cross-sectional and descriptive study was carried out on the cases of patients with Schwannoma over 14 years of age, diagnosed at the National Institute of Neoplastic Diseases from 2009 to 2023. Medical records and pathology reports were reviewed. Results: A total of 225 patients were diagnosed with schwannoma on anatomopathology. Median age was 44 years, with a range of 15 to 92 years. 135 (60%) patients were female and 90 (40%) male, with a ratio of 1.5:1. 19 (8.4%) patients had a second cancer before or after the diagnosis of schwannoma. 6 (2.66%) patients were previously diagnosed with neurofibromatosis. According to anatomical origin: 27 (12%) patients had schwanommas of the abdominal region, 36 (16%) of the head and neck, 42 (18.66%) of the spinal cord, 17 (7.55%) of the extremities, 83 ( 36.88%) of the intracranial region and 20 (8.88%) of the thorax. At the intracranial level, 71 patients had location at the cerebellopontine angle, 5 at the orbital level, 2 at the level of the cerebellum and 5 in another location. At the abdominal level, 13 patients had a retroperitoneal location, 8 at the gastric level, 2 at the renal level and 4 in another location. In 130 patients we can obtain the ki67, median score was 2% (1-50%). Regarding treatment, 156 (69.33%) patients underwent surgery, and 42 (18.66%) patients received radiation treatment. During their follow-up, only 5 (2.22%) patients had local recurrence. Conclusions: Schwannomas are rare benign tumors. In many cases, its suspected diagnosis is difficult due to its similarity to other tumors that must be part of the differential diagnosis. Its treatment is surgical, with the objective of complete macroscopic resection. Radiotherapy is a complementary treatment in case of residual disease.

Medical Management of Uterine Fibroids-A hope for Fertile Women!

Uterine fibroids or Myomas or Leiomyoma of uterus are the most common type of benign tumor of uterus and most common pelvic tumour in women with unclear etiology. Uterine fibroids or Myomas or Leiomyoma of uterus are the most common type of benign tumor of uterus. In India the incidence of fibroids is most common in women of 31- 40 years of age i.e. as more than 1/3 (35%) of them get affected. Recent understanding of etiology suggests increased number of estrogen and Progesterone Receptors, increased COMT gene expression and TGF-B3. Risk factors for developing fibroids are age, early age at menarche, reduced fertility, frequent caffeine consumption, obesity, hypertension, diabetes mellitus, alcohol consumption and previous pelvic inflammatory disease (PID). Rural women are at a much higher risk of uterine fibroids than urban women in India. (37.65% vs.24%) probably due to multiparty at a young age disturbing Estrogen and Progesterone Receptors. Treatment options for symptomatic uterine fibroids include medical, surgical, and radiologically guided interventions. Although curative treatment relies on surgical therapies- either myomectomy or hysterectomy, medical treatments are considered the first-line treatment to preserve fertility and avoid or delay surgery. Medical therapy is in nascent stage in India. Medical treatment must be individualized based on age, signs & symptoms, sustained reduction of the size and sustenance of fertility if desired with minimal side effects. Materials and Methods: This article is based on a literature review on medical therapy being tried on a case the author is managing now. The initial results are encouraging and need to monitor the reduction of the size or volume of the Fibroid in coming months.

Clinical case of treatment of giant uterine fibroid

Uterine leiomyomas are the most common type of benign tumor that occurs in the female pelvis. Uterine leiomyoma is a tumor of smooth muscles. Its prevalence is higher in the reproductive age group and decreases after menopause. Giant uterine fibroids are a rare tumor of the uterus. Giant uterine fibroids, especially subcutaneous types, are complicated by malnutrition due to deterioration of their blood supply. The complaints of the patients are non-specific: an increase in the size of the abdomen, aching pains, sometimes difficulty urinating and defecating. A physical examination reveals a giant abdominal and pelvic formation. Ultrasound with Dopplerometry and contrast-enhanced MRI diagnoses a giant tumor next to the uterus with a heterogeneous structure and the presence of cystic cavities, which is difficult to distinguish from a true large ovarian tumor. The article illustrates the complexity of differential diagnosis of giant tumor of the uterus and ovaries. There are no significant differences between these tumors during ultrasound and MRI examinations. The final diagnosis can be made intraoperativery. The article presents a clinical observation of the giant uterine fibroids of a 48-year-old female patient. Ultrasound and contrast-enhanced MRI revealed a giant tumor of the right ovary, which occupied the entire abdominal cavity, of a heterogeneous structure. Intraoperatively, two tumors, intimately adjacent to each other, 31 cm and 28 cm in diameter, emanating from the isthmus of the uterus, were found. The final diagnosis of uterine fibroids was established histologically. Difficulties in differential diagnosis between uterine fibroids and ovarian tumors before surgery are associated with the large size of the tumor and the heterogeneity of the structure due to its malnutrition.

MANAGEMENT OF MAMMARY FIBROADENOMA IN ROTTWEILER DOGS

Fibroadenoma mammae is a tumor that is formed from a mixture of fibrous and glandular tissue, usually known as a type of benign tumor that grows on mammae. The aim of this study is to report case management fibroadenoma in rottweiler dogs. A Rottweiler dog eight-year-old with a body weight of 24 kg, female sex with a lump in the left (sinistra) second mammary gland. A physical and clinical examination of the dog showed a healthy dog with a good appetite and drink, normal defecation and urination. Routine hematological examination showed an increase in MCV (Mean Corpuscular Volume) and a decrease in MCHC (Mean Corpuscular Hemoglobin Concentration), but not very significant. The results of histopathological examination of tumor tissue samples, the dog was diagnosed with fibroadenoma mammae with a fausta prognosis. Dogs are handled by performing surgery (excision) with the method of mastectomy (regional) to remove the tumor mass and give the antibiotics cefotaxim, cefixime with anti-inflammatory meloxicam, topical drugs such as Enbatic® and hematodin. After surgical removal of the tumor mass and administration of post-operative therapy, the case dog was declared cured with the surgical wound dry and fused on the fourteenth day. Handling fibroadenoma mammae it must be done as quickly as possible to prevent the tumor from metastasizing to other parts of the body.

Unicystic Ameloblastoma Mural Variant: A Case Report

Background: Ameloblastomas are a rare type of benign neoplastic tumors that are locally invasive and make up around 1% of all head-and-neck tumors. Mostly diagnosed in people between the ages of 30 and 60 years, it has a global incidence of about 0.5% of cases per million person years. Ameloblastomas are classified as multicystic, unicystic, peripheral, and desmoplastic variants. Unicystic ameloblastomas (UAs), accounting for about 6% of the cases, have a high recurrence rate. It is histologically divided into luminal, intraluminal, and mural types. As the mural variant is aggressive and has the highest chance of recurrence, radical resection of tumor is required. Case Presentation: A case of 47-year-old patient, diagnosed as unicystic mural variant of ameloblastoma presented to us in March 2023 at the department of head-and-neck surgery at a tertiary care setup in Karachi, Pakistan. Postoperatively, the patient is now on 6-month follow-up with no residual or recurrence report as of yet. Conclusion: We report a rare case of UA mural variant in the right mandible, which highlights the importance of prompt diagnosis and treatment of this type of ameloblastoma, particularly in a location where they can cause significant damage.

The role of fine-needle aspiration biopsy in the diagnosis of malignant tumors.

Cytopathology and histopathology play a key role in the process of diagnosing oncological diseases and premalignant conditions. Fine-needle aspiration (FNA) is one of the techniques used for obtaining biopsy of a wide variety of body tissues, causing patients minimal discomfort. Therefore, it is often considered to be the best strategy for investigating and diagnosing some precancerous or potential malignant lesions. Being successful as a means of confirming the clinical suspicion of metastatic recurrence in the cases of an already known cancer, the interest has further focused on the preliminary diagnosis of various types of benign or malignant tumors. In cases of inoperable tumors, this technique is useful for formulating the final diagnosis. FNA biopsy proved its effectiveness as a highly accurate, cost-effective, and safe technique, with potential high diagnostic yield. Immunohistochemistry, used as an additional tool to classical histopathological examination, remains a very practical and reliable technique that promises good results especially in determining the site of origin within metastatic disease.

Ancient schwannoma in posterior triangle of neck: a rare tumor case report and literature review

Ancient Schwannoma is a rare variant of Schwannomas, a type of benign nerve sheath tumor arising from Schwann cells, hence giving it its name Schwannoma. The term ancient represents the tumor undergoing degenerative changes such as calcification, hyalinization, hemorrhage, cystic degeneration and necrosis and characteristically the loss of Antoni type A tissue. This case report describes a patient having an ancient schwannoma and the management done. Detailed management and findings starting from history and extending to USG, FNAC, CT scan, MRI and excisional biopsy have been described with positive findings supporting the diagnosis like presence of degenerative material in FNAC, peripheral enhancement on CT with the classical Target sign also visible on MRI. The following case reports helps to show how to connect the dots of different findings that may start from the patient’s basic history to eventual confirmation by biopsy.
