Preferred Label : hemangiopericytoma;
Definition : A tumor composed of spindle cells with a rich vascular network, which apparently arises
from pericytes, cells of smooth muscle origin that lie around small vessels. Benign
and malignant hemangiopericytomas exist, and the rarity of these lesions has led to
considerable confusion in distinguishing between benign and malignant variants. (From
