Abstract

Hemangiopericytoma is a rare neoplasm that originates from small peri-capillary spindle shaped cells called pericytes. The most common sites of origin are the thigh, the pelvis and the retroperitoneum. A primary pulmonary hemangiopericytoma is particularly unusual. However, more than 50% of hemangiopericytoma cases metastasize to the lungs, the bone, and the liver. A long-term clinical and radiological follow up is recommended due to the high risk of recurrence of a potential malignancy. We report a case of a metastatic hemangiopericytoma in the lung that had initially developed in the thigh of a 53 year-old woman 6 years ago. The authors emphasize the long-term follow-up of this type of rare sarcoma.
