A hemangiopericytoma, 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 are believed to arise from the pericytes of Zimmerman. Histologically, this tumor demonstrates great variability and clinical course cannot be predicted from the histological appearance. The hemangiopericytoma in head and neck region appears to be a lower grade malignancy with frequent local recurrency and metastasis, therefore, aggressive surgical therapy should be the treatment of choice. We experienced two cases of hemangiopericytoma occurred in the right skull base area presenting as neck mass and report them with a review of literatures.
