Squamous Cell Carcinoma Arising in Mature Teratoma of the Ovary Masquerading as Abdominal Tuberculosis.

Pure squamous cell carcinoma (SCC) of the ovary is rare. SCC can arise in a mature teratoma (MT), ovarian endometriosis or in a Brenner tumor. SCC is the most common malignant transformation arising in MT and comprises 80% of all cases.

Cytohistological Features of Spindle Cell Lipoma- A Case Report with Differential Diagnosis.

Spindle Cell Lipoma (SCL) is an uncommon benign tumour of adipose tissue that is usually superficially located in the neck, back and shoulder region. Although it has characteristic histological features it can pose a diagnostic dilemma on cytology. It presents with a mixture of spindle cells, adipocytes, collagen fibres and a myxoid matrix in varying proportions sometimes with mild pleomorphism.

Symptomatic improvement with gluten restriction in irritable bowel syndrome: a prospective, randomized, double blinded placebo controlled trial.

Background/aims: The existence of non-celiac gluten sensitivity has been debated. Indeed, the intestinal and extra-intestinal symptoms of many patients with irritable bowel syndrome (IBS) but without celiac disease or wheat allergy have been shown to improve on a gluten-free diet. Therefore, this study set out to evaluate the effects of gluten on IBS symptoms.

A rare case of malignant paraganglioma of urinary bladder.

Paraganglioma of the urinary bladder is a rare pathologic entity with no definitive histological, immunohistochemical or molecular features to determine its malignant potential. Malignancy is essentially determined by the presence of deep local invasion, invasion of adjacent structures and lymph node or distant metastases. So far, up to 180 cases of paraganglioma have been reported, with <30 being malignant.

Omental sclerosing extramedullary hematopoietic tumors in Janus kinase-2 negative myelofibrosis: caveat at frozen section.

Sclerosing extramedullary hematopoietic tumors (SEMHTs) are associated with chronic myeloproliferative neoplasms. These extremely rare mass lesions were first described in kidney and peritoneum. On histopathology, they are characterized by sclerosis, entrapped fat, atypical megakaryocytes with myeloid and erythroid elements.

Cytological diagnosis of Langerhans cell histiocytosis with cutaneous involvement.

Langerhans cell histiocytosis (LCH) is a rare disease affecting predominantly children. The course of the disease varies, from spontaneous resolution to a progressive multisystem disorder with organ dysfunction and potential life-threatening complications. Diagnosis of LCH is often difficult and may be delayed because of its rarity and especially so if it occurs with unusual presentation.

Primary cryptococcal prostatitis--rare occurrence.

Cryptococcosis is a well recognized infection in immunocompromised patients. Cryptococcal infection primarily involves the lung and is hematogeneously spread to other organs. Sometimes it might affect the genitourinary tract.

Evaluation of non cyanide methods for hemoglobin estimation.

Background: The hemoglobincyanide method (HiCN) method for measuring hemoglobin is used extensively worldwide; its advantages are the ready availability of a stable and internationally accepted reference standard calibrator. However, its use may create a problem, as the waste disposal of large volumes of reagent containing cyanide constitutes a potential toxic hazard.

Aims And Objective: As an alternative to drabkin`s method of Hb estimation, we attempted to estimate hemoglobin by other non-cyanide methods: alkaline hematin detergent (AHD-575) using Triton X-100 as lyser and alkaline- borax method using quarternary ammonium detergents as lyser.

Fine needle aspiration cytology of epididymal nodules.

Background: The incidence of non neoplastic lesions are much more common in epididymis. Clinically, epididymal nodules are easily accessible to fine needle aspiration cytology (FNAC) procedure. There are very few literature reports documenting the role of cytology in evaluation of epididymal nodules.

Idiopathic renal replacement lipomatosis: a case report and review of literature.

Idiopathic renal replacement lipomatosis is a rare condition in which the renal parenchyma, especially the renal sinus is replaced with adipose tissue with increase in perirenal fat. We report a case of renal replacement lipomatosis presenting as a renal mass clinically. The computed tomography scan revealed low density and nodular masses of adipose tissue within the renal parenchyma.

Mucinous adenocarcinoma of the renal pelvis with pseudomyxoma peritonei.

Mucinous adenocarcinoma of the renal pelvis is an extremely rare tumor with very few case reports in literature. Pseudomyxoma peritonei is an uncommon condition characterized by the presence of mucinous gelatinous material in the peritoneal cavity. It occurs secondary to primary mucinous neoplasms of particularly the appendix and the ovary.
