[Renal hemangiopericytoma. Anatomo-pathologic and clinico-therapeutic considerations. A case report]

The Authors report a case of renal hemangiopericytoma, whose interest is related to the extreme rarity (24 cases reported until today), its insidious growth, the late in diagnosis, its uncertain clinical-biological evolution, not always predictable. Considering chemotherapy and radiotherapy ineffectiveness, an adequate treatment for such a neoplasm requires the surgical therapy, which must be followed by a careful follow-up.
