Malignant fibrous histiocytoma arising in a thoracotomy scar.

Malignant fibrous histiocytoma arises most commonly de novo and rarely from sites of chronic inflammation. The authors present a case of malignant fibrous histiocytoma arising in a thoracotomy hypertrophic scar. The patient required large local excision of the tumor down to and including the muscle layer with postoperative radiation treatment. Factors associated with the occurrence of this sarcoma are discussed along with salient management principles.
