Creutzfeldt-Jacob disease: An autopsy case report in tertiary care hospital.

Sporadic Creutzfeldt-Jakob disease (CJD) is the most common prion disease. It is a rare, fatal neurodegenerative disease caused by an infectious protein called prion. The diagnosis can be confirmed only by histological examination of brain tissue. Because of the transmissible nature of the disease, autopsy or brain biopsy cannot be performed at many institutions. Histology shows spongiform changes, neuronal loss, reactive astrocytic proliferation, accumulation of pathologic protein occurring in three general forms: Sporadic, familial, and acquired form, including a variant form of CJD. It clinically presents as predominantly progressive dementia with a rapid onset, myoclonus, cerebellar, pyramidal, extra pyramidal and visual signs. Occurrence of periodical spikes in electro-encephalogram, observation of cortical signal alterations in magnetic resonance imaging (MRI) studies, and detection of protein 14-3-3 in cerebrospinal fluid substantiate diagnosis. Autopsy case is presented of a 50 year old woman with progressive dementia, typical neurological symptoms, MRI findings and confirmation of CJD on histology and immunostaining.

Leiomyosarcoma of the renal pelvis.

Leiomyosarcomas are rare malignant tumors of the kidney. They may arise from the renal capsule, renal vein, renal pelvic musculature or renal parenchyma. Renal pelvis is an uncommon site of occurrence, with around 10 cases reported in the literature so far. Here we present a 60-year-old male who presented with increased urinary frequency, lower limb weakness, anorexia and weight loss. Imaging showed a right renal mass. A renal cell carcinoma was suspected clinically. A right nephrectomy was performed, which showed a large circumscribed mass in the hilar region. Histology revealed a tumor mass arising from the renal pelvis. The tumor was composed of spindle cells arranged in fascicles. Immunohistochemistry showed tumor cells to be positive for smooth muscle actin (SMA) and desmin (Des) and negative for cytokeratin (CK), HMB 45, CD117 (C-kit), and CD34. That confirmed the diagnosis of leiomyosarcoma.

Breast hamartoma associated with pregnancy--a case report.

Hamartoma of the breast is an uncommon tumor like condition constituting only 3.9 to 4.8 % of benign breast tumors. We wish to report clinical, cytological, cytological histological findings of breast hamartoma with pregnancy
