Malignant fibrous histiocytoma of the pulmonary artery: a case report

We recently experienced a case of primary malignant fibrous histiocytoma of the left pulmonary artery occurred in a 27-year-old man who had 5 months history of intermittent hemoptysis. Chest X-ray revealed multilobulated mass density(about 4x5cm in size) in left hilar area, and another small lobulated nodular density (about 1×1.5cm insize) in left upper lung field, which was intrapulmonary metastatic deposit. CT scan, pulmonary arteriography, andselective left bronchial arteriography after partial resection of the left hilar mass and left upper lobectomy revealed the mass to have the characteristic feature.
