Abstract

Hemangiopericytoma is regarded as a benign neoplasm originating from the pericyte, a contractile cell surrounding small blood vessels. Historically, the histopathologic diagnosis of hemangiopericytoma was based solely on the presence of thin-walled staghorn branching vessels surrounded by numerous round-to-spindle monomorphic tumor cells. However, more studies have emerged raising the skepticism of the nature of the pericyte itself as well as the existence of this tumor. Current concept of the diagnosis of this tumor has significantly changed as acknowledged by the recent WHO classification of soft tissue tumors. Most tumors previously diagnosed as hemangiopericytoma were reclassified into other tumor groups, the most important of which is solitary fibrous tumor. In this review, controversial issues regarding hemangiopericytoma are discussed. The general characteristics as well as oral manifestations of all reported solitary fibrous tumor cases are presented.
