Malignant fibrous histiocytoma arising in a patient with multiple neurofibromatosis: a case report and a literature review.
A case report of a 56-year-old man with the characteristic clinical and histologic features of multiple neurofibromatosis is presented. This patient was also diagnosed as having a malignant fibrous histiocytoma involving the right thigh with metastasis to the lung. A definite association between Von Recklinghausen's disease and various sarcomas (most commonly neurofibrosarcomas) of the peripheral nerves and the somatic soft tissues is well-known. This is apparently the first report in the literature of a malignant fibrous histiocytoma arising in a patient with multiple neurofibromatosis. The phenomenon of sarcomatous change in Von Recklinghausen's disease and the clinical and pathologic features of malignant fibrous histiocytoma are also discussed.
