Renal hemangiopericytoma. Case report and review of the literature.

Overview

Hemangiopericytoma (HPC) is an uncommon tumor which was first described in 1942. There are no unique radiological or clinical identifiers that can reliably aid in preoperative diagnosis. Surgery is the only reliable therapy as both chemotherapy and radiotherapy have proven ineffective in several series. The outcome is difficult to predict; the only reliable predictor is the presence or absence of metastasis. We report on a 63-year-old female with a large left renal HPC.
