A case of malignant fibrous histiocytoma in the lung--resembling recurrent pulmonary thromboembolism.
Malignant fibrous histiocytoma (MFH) can be classified as a pleomorphic mesenchymal sarcoma which occurs most commonly in the extremities and retroperitoneum. We report a very rare case of MFH presumably originating in the pulmonary artery and resembling recurrent pulmonary thromboembolism. MFH was suggested by transbronchial biopsy and confirmed by open lung biopsy. Obstruction of the right main pulmonary artery and stenosis of the left main pulmonary artery was confirmed by pulmonary angiography.
