Abstract

Hamangiopericytoma, first described by Stout & Murray in 1942, is a rare vascular tumor composed of spindle-shaped or rounded cells proliferating around endothelial lined capillaries. These proliferating cells were belived to arise from the pericytes of Zimmerman. Histologically, this tumor demonstrates great variability and clinical course cannot be predicted from the histological appearance. Head and Neck hemangiopericytoma appears to have a lower grade malignancy with frequent local recurrency and metastasis, therefore, aggressive surgical therapy should be the treatment of choice. We experienced a case of hemangiopericytoma occurred in the right skull base at submastoideal and suboccipital area presenting as neck mass in upper occipital triangle in a 42 years old female patient and we report it with a review of literatures.
