Hemangiopericytoma of the lung is a very rare malignant tumor despite it's high vasculities of the lung, because, this tumor arises from the pericytes enveloping capillaries. A pulmonary hemangiopericytoma was diagnosed in a 63-year-old female who had complained of cough, sputum, and intermittent chest pain for about 8 years. She was admitted to our hospital, because of progressive severe dyspnea on exertion and orthopnea for about 3 months. She was taken explothoracotomy and left pneumonectomy including evacuation of lots of blood clots due to ruptured large tumor and ineffective drainage with closed thoracic tube. She was discharged at post-operative 7 days under very good condition. She has been treated with radiotherapy&chemotherapy since then.
