Abstract

Malignant fibrous histiocytoma (MFH), also known as undifferentiated high grade pleomorphic sarcoma, accounts for 20–24% of all soft tissue sarcomas in the US. Peak incidence is in the fifth and sixth decades of life, with a 2:1 male to female distribution. MFH is usually seen in the soft tissues of the extremity and involvement of the lung is rare. We report a case of pleural MFH in a patient with previous pleuro-pulmonary tuberculosis for which he had a lobectomy.
