Thin-walled, branching blood vessels, also known as “staghorn” vessels, are characteristic of hemangiopericytomas. Nuclei are often ovoid or spindle shaped. Hemangiopericytoma is a term formerly used to describe a continuum of mesenchymal tumors with elevated cellularity found throughout the body in soft tissue and bone.
