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. 4.5).

Thin-walled, branching blood vessels, also known as “staghorn” vessels, are characteristic of hemangiopericytomas. Nuclei are often ovoid or spindle shaped. In particular, questions exist regarding the synonymity of a hemangiopericytomatous growth pattern--defined by a monomorphic population of compact polygonal or bluntly fusiform cells and a branching stromal vascular pattern with a "staghorn" configuration--and the presence of a reproducible biological entity. Hemangiopericytoma is a term used to described a group of tumors that are derived from pericytes, the cells normally arranged along specific types of blood vessels called capillaries and venules. These types of tumors are typically slow-growing, may be either benign (non-cancerous) or malignant (cancerous), and may occur anywhere in the body. Thyroid gland - Hemangiopericytoma.
