Primary renal teratoma: a rare entity

ABSTRACT: Teratomas are neoplasms that arise from pluripotent cells and can differentiate along one or more embryonic germ lines. Renal teratoma is an exceedingly rare condition. Teratomas commonly arise in the gonads, sacrococcygeal region, pineal gland, and retroperitoneum. They present mainly as an abdominal mass with few other symptoms. Majority of the tumors are benign, situated on the left side and para renal, occasional lesions are bilateral. If diagnosed early, they are amenable to curative excision. Renal teratomas are rare and most have been dismissed as cases of teratoid nephroblastomas or retroperitoneal teratomas secondarily invading the kidney. The differentiation between these two neoplasms in the kidney is often problematic. We present a case of intrarenal immature teratoma in a six-month-old baby girl.

Eccrine carcinoma : a rare cutaneous neoplasm

Abstract Eccrine carcinoma is an extremely rare malignancy of the skin with few well documented cases reported in the literature. It is frequently found on the lower extremities, and it equally affects both sexes in the sixth and seventh decade. In our case, we present a 46- year-old female with a recurring exophytic tumor on the right lower extremity, without local extension. The initial tumor was biopsied, excised and diagnosed as an eccrine carcinoma.
