Malignant fibrous histiocytoma (MFH) cases are classified within the group of nonclassified sarcomas. The etiopathogenesis is unclear; however, MFH commonly develops in scar tissue and in areas exposed to radiation. MFH is the most common soft tissue sarcoma in adults and may be borne in the lungs, chest wall, mediastinum, or other tissues. Primary MFH of the lung constitutes less than 0.2% of all pulmonary neoplasms; thus, an optimal treatment strategy has not yet been elucidated. We aimed to report a case of MFH of the lung with subsequent treatment administration.
