Hemangiopericytoma was first reported by Stout and Murray in 1942, when it was thought that the tumor originated from the pericyte first described by Zimmermann in 1923. This tumor is considerably less common than the other vascular tumors and seldom occurs in the head and neck region. While this tumor is usually regarded as benign, it sometimes shows metastasis and malignant degeneration. Zimmermann thought that the pericyte existed around the capillaries, enveloping them with cytoplastic processes. Moreover, he thought the pericyte might have been modified from smooth muscle cells. Generally, this tumor histologically resembles other vascullar tumors such as Glomus tumor, Hemangioendothelioma, and Vascular leiomyoma, so the primary problem was the differential analysis of the original development of the tumor cell. Despite the many theories expressed on the subject since the original report, there has been no final determination of the tumor histology. In this instance, a case of hemangiopericytoma in a 53-year-old female was found to have progressed in the right cheek region for 20 years. The tumor was excised and the operation wound treated with plastic surgery by the rotation and advancement of the cheek skin flap. After consideration of the literature, following histopathological examination by optical and electronmicroscopes, it was determined that this tumor belonged to the benign hemangiopericytoma of Battifola type A. However, no final conclusions as to the tumors histology were possible from the original analysis. The details of this case are as follows.
