The Hemangiopericytoma tumor can occur anywhere in the body. Muscle tissues are most frequently affected, whereas subcutaneous and dermal hemangiopericytoma tumor growth is less frequent 3,5. Hemangiopericytoma (HPC) is an uncommon neoplasm characterized by a dense, blunt spindle-cell proliferation with a richly vascular stroma. Supporting blood vessels often assume a staghorn configuration. The ovoid tumor cells of hemangiopericytomas are rather nondescript and may cause confusion with those of other soft tissue tumors (Fig.
