Hemangiopericytoma is a rare vascular tumor arising from pericytes. The tumor usually develops in the skin or subcutaneous tissue, particularly in the extremities.4 pulmonary origin of hemangiopericytoma is known to be quite rare. It has the potential to become a highly malignant lesion, so wide excision is the treatment of choice. We present a case of primary malignant hemangiopericytoma of the lung and discuss the clinical symptoms, diagnosis, therapy and prognosis within the context of a brief review.
