Malignant fibrous histiocytoma of the lung in a patient with a history of asbestos exposure.

Malignant fibrous histiocytoma is one of the most common soft-tissue sarcomas in adults, usually occurring in the extremities, retroperitoneum, and trunk [1 ]. Metastasis to the lung is common; however, primary malignant fibrous histiocytoma in the lung is extremely rare. We report a case of primary malignant fibrous histiocytoma in the lung and review the clinical and radiographic findings. To our knowledge, the present case is the first documentation of pulmonary malignant fibrous histiocytoma in a patient with a history of asbestos exposure.
