Hemangioperycytoma is a rare perivascular tumor that seldom involves the urogenital system. This tumor often appears with an unspecific clinical picture, and sometimes is associated with hematuria or hypertension. Diagnosis is based on a combination of histological and immunohistological findings. We report a case of a 52-year-old patient with renal hemangiopericytoma who underwent surgical treatment at our service. This report also includes a literature review on the subject.

Hemangioblastomas (HBs) are highly vascularized, slow-growing, rare benign tumors (WHO grade I). They account for about 2% of intracranial neoplasms; however, they are the most common primary cerebellar tumors in adults. Another frequent seat is the spinal cord (2-10% of primary spinal cord tumors).
