[Malignant fibrous histiocytomas].

Malignant fibrous histiocytomas of the storiform pleomorphic type were found in the lower legs of two patients, 79 and 42 years of age. In the first, dermatofibrosarcoma protuberans, in the second, squamous cell carcinoma, had to be discussed. In the first patient, the tumor arose in the area of a preexisting paresis of the superficial peroneal nerve; the second patient developed the tumor in fistulous osteomyelitis existing since childhood.
