Malignant abdominal hemangiopericytoma. Case report.

A case of malignant abdominal hemangiopericytoma in a 74-year-old man is presented. The tumor was surgically removed. A large local recurrence and a minor abdominal metastasis were excised 5 years later. The patient is well and apparently tumor-free 6 months post-operatively. Other methods of treatment are discussed.
