Dilated, branching, hyalinized staghorn-like (hemangiopericytoma-like) vasculature Hyalinized to collagenous stroma, sometimes with streaming of cells between collagen Myxoid changes can be prominent (Mod Pathol 1999;12:463) Lipomatous variant contains variable amount of fat (Am J Surg Pathol 1999;23:1201) General Pathology Cells in hemangiopericytomas are derived from pluripotent perivascular mesenchymal cells and resemble pericytes, with few cytoplasmic organelles. 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.

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. 4.5).
