Malignant fibrous histiocytoma and squamous carcinoma derived from a burn scar

Abstract

Malignant fibrous histiocytoma is the most common type of soft tissue sarcoma in late adult life. The tumour may be seen rarely in burn scars and accompanying other kinds of malignancies. We herein report a case of a tumour that derived from an old burn scar on the scalp. The histological examination revealed that the tumour contained both malignant fibrous histiocytoma and squamous carcinoma areas. Malignant transformation in a burn scar is a well-known development; therefore, a new lesion occurring within the scar should not be neglected.
