Hemangiopericytoma is a mesenchymal neoplasm originating from the pericyte, a cell type that surrounds the capillaries. Its primary localization in the lung is extremely rare. A 70-year-old woman was referred to our hospital complaining of cough and non-massive hemoptysis from 2 months earlier. She was a nonsmoker with a history of close contact with sheep and a dog. On physical examination, she had reduced respiratory sounds in the left upper zone. Her chest x- ray revealed a mass in the left middle and upper zones. CT-scan of the lungs revealed a parenchymal mass with -4 to 20 (HU) densities. Hemagglutination test was negative for hydatid cyst. Fiberoptic bronchoscopy was normal; therefore, the patient underwent surgical operation. The pathology of the mass was primary pulmonary hemangiopericytoma. (Tanaffos 2009; 8(2):59-63)
