Metastatic renal hemangiopericytoma: A rare case report
Abstract
The hemangiopericytoma (HPC) of the kidney is extremely rare perivascular neoplasm. There are no specific radiological or clinical findings that can aid in preoperative diagnosis. In the world literature, only 41 cases of renal HPC have been previously documented. We report on a 56-year old woman with renal HPC of the right kidney who had lung metastasis at the time of diagnosis. The right radical nephrectomy was performed and the combination chemotherapy was given, postoperatively. After 3 cycles of chemotherapy, disease was stable, but progression was seen at the end of 6 courses of chemotherapy. The patient died due to progression of disease ten months later after the diagnosis. We suggested that for patients present with renal mass, renal HPC as well as the other renal tumors should be considered in the differential diagnosis.
