Multicentric malignant fibrous histiocytoma of soft tissue.

We present an unusual case of multicentric malignant fibrous histiocytoma of soft tissue. Over the past 24 years, a 67-year-old woman developed malignant fibrous histiocytoma in four different soft-tissue sites. There were two local recurrences of one of the tumors. Currently, there is no evidence of visceral involvement. The evidence suggests that this patient has a predisposition of the connective tissue to develop malignant tumors of fibrohistiocytic differentiation.
