Hemangiopericytoma ischiorectal. Report of a case

Hemangiopericytoma (HP) is a rare tumoral neoplasm of the soft tissues. Here, we report a case of HP that appeared in a young woman in a very uncommon location (perianal). Initially it was considered as a perianal abscess: arteriography, CT-scan and, eventually, histological studies, confirmed the diagnosis of HP. The tumoral mass was first embolized and thereafter was resected through a double approach (abdominal and perineal). One and a half years after surgery, the patient remains asymptomatic.
