Background: Sialoblastoma is an uncommon salivary gland neoplasm seen predominantly in the paediatric age group. It poses diagnostic challenges to the pathologists because of its rarity.

Case Report: Here, we present the cytological features of a case of sialoblastoma in 5-month-old baby boy on imprint cytology.

A rare case of complicated typhoid fever presenting with secondary Hemophagocytic Lymphohistiocytosis.

Enteric fever is one of the important causes of tropical fever with a prevalence of 11-21 million cases worldwide annually. It encompasses both typhoid and paratyphoid fever. Typhi is the causative organism for typhoid fever, manifesting as an uncomplicated febrile illness to life-threatening sepsis with multiorgan dysfunction.

Pulmonary thromboembolism-a rare presentation for Strongyloides hyperinfection in an immunocompetent patient.

Pitfalls in Cytological Diagnosis of Extra Adrenal Paraganglioma and Pheochromocytoma: Experience From a Tertiary Care Center.

Background: Pheochromocytoma and extra-adrenal paragangliomas increasingly coming into light nowadays because of improved imaging techniques and biochemical investigations. There is sparse literature available regarding cytological findings of adrenal and extra-adrenal paragangliomas.

Material And Methods: We studied 16 cytological specimens retrospectively over a period of 3 years, where subsequent histological diagnosis of phaeochromocytoma or paraganglioma was available.

Virilizing adrenocortical carcinoma in a female child of Li-Fraumeni syndrome.

Adrenocortical carcinoma is a rare malignancy and even rarer in infancy. Most of these tumors in the pediatric age group are hormonally active and predominantly present with virilization. We report a case of a 1-year-3-month-old female child presenting with virilization.

Clinicopathological profile of ependymomas with special reference to survival data - Experiences of a tertiary care center'.

Background And Aims: Ependymomas exhibit heterogeneity across age, location, histology, molecular nature and survival suggestive of an epigenetic component in its pathogenesis. The CNS WHO classification (2021) classifies ependymomas based on DNA methylation profiles. Studies suggest that molecular sub-types remain stable throughout the course of disease.

Clinicopathological study of adrenal pheochromocytoma and extra-adrenal paragangliomas with reference to GAPP and PASS scoring systems.

Background: The presence of distant metastasis is known to drastically reduce survival of adrenal pheochromocytoma (PH) and extra-adrenal paraganglioma (PGL). Therefore, predicting malignant potential has an immense impact on prognosis. Pheochtomocytoma of adrenal gland scaled score (PASS) and the grading of adrenal pheochromocytoma and paraganglioma (GAPP) score are two histological algorithms used to predict metastatic potential, but neither has been regarded as 'gold-standard'.

Myasthenia gravis with Castleman disease: A case report with review of literature.

Myasthenia gravis is an autoimmune disorder caused by the formation of autoantibodies directed against the synapses of neuromuscular junction. It is most commonly associated with other non-thymomatous lesions. Castleman disease is one of them, which is a benign lymphoproliferative disorder of uncertain origin.

Metastatic Neuroblastoma in the Testis: Report of a Case with Review of Literature.

Neuroblastoma is the most common extracranial malignant solid tumor in childhood. Neuroblastoma is known to metastasize in certain niche areas such as the bone, bone marrow, liver, and skin. Testicular metastasis of neuroblastoma is uncommon, and only a few cases have been reported.

Biliary atresia with splenic malformation with associated ductal plate malformation and duodenal atresia: A case report.

Biliary atresia (BA) is the most common cause of the obstructive type of neonatal cholestasis that requires prompt surgical intervention. About 10% of neonates with BA have other congenital anomalies, of which splenic malformation (BASM) is a well-known distinct sub-group. There is sparse literature on the association of duodenal atresia and ductal plate malformation (DPM) in patients of BASM.

MiT family translocation-associated renal cell carcinoma: A report of two cases in children.

Renal cell carcinoma is uncommon in children and must be distinguished from the more common Wilms' tumor. Here, we present two cases of renal cell carcinoma in children both of whom presented with hematuria. Accurate diagnosis is essential in order to differentiate it from epithelial predominant Wilms' tumor which has vastly different prognosis and treatment.

Primary hepatic leiomyosarcoma masquerading as focal nodular hyperplasia of liver: A wolf in sheep's clothing.

Primary hepatic leiomyosarcoma is a rare hepatic malignancy which requires exclusion of other primary site of origin. Clinical presentation and imaging of this tumor is nonspecific and mimics many other hepatic neoplasms. A 62-year-old female patient presents here with right hepatic mass with insidious onset and radiological features favoring a benign solid lesion suggestive of focal nodular hyperplasia.

A case of superficial CD34 positive fibroblastic tumor: Diagnostic challenges and pitfalls.

Superficial CD34 positive fibroblastic tumor (SCPFT) is a recently described soft tissue tumor of intermediate grade with predilection for subcutaneous and superficial fascial planes. Morphological diagnosis of these tumors can be challenging because of overlapping features with other benign and malignant soft tissue tumors of fibroblastic and myofibroblastic origin. A middle-aged man came with a subcutaneous mass in the left thigh.

Differentiating biliary atresia from other causes of infantile cholestasis: An appraisal of the histomorphological changes on liver biopsy.

Background: Cholestatic disorders are a significant cause of morbidity and mortality in infants. Characterization of these disorders and differentiating biliary atresia (BA) from other causes of intrahepatic cholestasis is an age-old problem.

Objectives: To study the spectrum of different infantile cholestatic disorders in our population, to differentiate BA from other causes of neonatal cholestasis (NC) on a liver biopsy, and validation of the available scoring system for the characterization of these disorders.

Quest to develop a standard screening method for urothelial carcinoma using liquid-based cytology (The Paris System) and CK20.

Background: Bladder cancer, the most common malignancy of the urinary tract is a leading cause of morbidity and mortality. But cystoscopy, which is till now the mainstay of screening, is an invasive, high-cost method with low sensitivity especially for flat lesions.

Aim: To find a non-invasive and effective screening method with liquid-based cytology (LBC) using The Paris System (TPS) and CK20 immunocytochemistry.

Testicular Mixed Teratoma and Yolk Sac Tumor, Prepubertal Type: A Case Report with Summary of Prior Published Cases.

Background: Testicular mixed germ cell tumor is common in the post-pubertal age, less so in prepuberty. There are only 3 reports of prepubertal mixed teratoma and yolk sac tumor. Two of these cases had immature teratoma component and were in the neonatal age group.

Cytological findings of phosphaturic mesenchymal tumor: Report of a case with summary of prior published cases.

Phosphaturic mesenchymal tumor (PMT) is a rare neoplasm causing tumor-induced osteomalacia (TIO) and is characterized by secretion of FGF23, renal phosphate wasting and hypophosphataemia. It can be completely cured by resection and therefore its diagnosis is of utmost importance. Although the histology is well described, there is sparse literature on cytology of PMT and only three cases have been described so far.

Labial Lipoblastoma in an Infant: An Uncommon Tumor at an Uncommon Site.

Lipoblastoma and lipoblastomatosis are benign fatty tumors of soft tissues that are unique to childhood. Occurrence of lipoblastoma in the labial region is infrequent and can cause diagnostic dilemma. Awareness about this entity is important to avoid hazardous treatment in young children.
