Hemangiopericytoma of kidney: case report and review of the literature.

Hemangiopericytoma, which is derived from pericytes, is rarely seen in the kidney and adical nephrectomy with or without chemotherapy is the treatment of choice in most of the cases. We report a fifty-year-old male patient presenting with gross hematuria that radiologic evaluation confirmed due to a solid mass in the right kidney. Its clinical manifestations and radiologic tests were similar to renal cell carcinoma. Radical nephrectomy was performed and the pathological examination revealed the specimen as hemangiopericytoma. No additional treatment was added and the patient remained disease free at the end of the first year follow up after radical nephrectomy.
