Primary Adult Renal Ewing's Sarcoma: A Rare Entity.

Ewing's sarcoma/primitive neuroectodermal tumors are high-grade small round blue cell tumors traditionally found in children and adolescents.These tumors primarily affect the bone and soft tissue, with extraskeletal sites rarely being affected. The clinical presentation and imaging findings are non-specific and are not characteristic.

Metanephric Adenoma with cystic changes- An uncommon presentation of a rare tumor in a young adult.

Metanephric adenoma (MA) is a rare benign neoplasm of the kidney that is usually asymptomatic and incidentally diagnosed. MA usually present as a solid mass; however, a cystic presentation has been reported. The main differential diagnosis of MA is the epithelial predominant Wilms tumor (e-WT) and the solid variant of papillary renal cell carcinoma (pRCC).

Pediatric multifocal histiocytic sarcoma- a fatal diagnosis not to miss!

Histiocytic sarcoma (HS) is a rare hematolymphoid malignant neoplasm with an aggressive clinical course. It can arise de novo or from low-grade B-cell lymphoma. We describe the case of a 16-year-old boy referred to our hospital with generalized lymphadenopathy, weight loss, and decreased appetite for one month.

Down syndrome presenting with different hematological manifestations: A case series of four cases.

Children with Down syndrome (DS) are found to have an increased risk of developing various hematological disorders. Particularly, they have an increased predisposition to acute leukemia, predominantly the myeloid type known as myeloid leukemia of Down syndrome (ML-DS). The major morphological subtype is acute megakaryoblastic leukemia.

Pediatric Granular Cell Tumor of the Breast: An uncommon neoplasm in an uncommon site and age group.

Granular cell tumor (GCT) is a rare soft tissue neoplasm of Schwann cell origin. Most cases occur in adults; however, the precise incidence is unknown in children. GCT is usually a slow-growing, painless tumor involving the skin and soft tissues that is mostly located in the head and neck region, especially the tongue.

Intraoperative Cytology of Ovarian Neoplasms with an Attempt to Grade Epithelial Tumors.

Background: Intraoperative cytology (IOC) is a simple and quick technique with excellent preservation of cellular details. In the present study, we have evaluated the role of IOC by various methods of smear preparation and compared it with frozen section diagnosis. A scoring system was followed for epithelial tumors for characterization and grading on the basis of cellularity, pattern, nuclear, cytoplasmic features, and background details.

Extramedullary Haematopoiesis in a Case of Pilomatricoma.

Pilomatricoma is a benign follicular skin appendage tumour. It usually occurs as solitary lesion and is most commonly seen in the face and upper extremeties. Here we report a rare case of extramedullary haematopoiesis (EMH) in pilomatricoma in a 38-year-old lady.
