title: [Giant retroperitoneal hemangiopericytoma: a new case].
abstract: Hemangiopericytomas are a rare vascular tumours that are derived from Zimmermann pericytes. Retroperitoneal hemangiopericytoma is usually bulky, clinical silent, and malignant. We present a 48 years old man, with compressive symptoms and a painless mass due to a giant retroperitoneal hemangiopericytoma weighing 3 kg. We are prompted to present this case as it is believed to be the largest hemangiopericytoma reported to date.
