Myxoid variant of dermatofibrosarcoma protuberans with fibrosarcomatous areas.
A case of dermatofibrosarcoma protuberans in a 39-year old woman excised from the right subclavicular region is described. Beside the typical storiform cellular pattern characteristic of dermatofibrosarcoma protuberans, a considerable part of the tumour displayed a myxoid change. Another part of the tumour exhibited large areas with a fibrosarcoma-like pattern. The transitional areas between these myxoid and fibrosarcoma-like areas resembled a poorly differentiated spindle cell sarcoma. Two years later the tumour recurred. The remarkable feature of the recurrent tumour was the occurrence of multiple giant cells identical to those seen in giant cell fibroblastoma.
