Dermatofibrosarcoma protuberans with lymph node involvement. A case report of simultaneous occurrence with an atypical fibroxanthoma of the skin.
A 40-year-old man had dermatofibrosarcoma protuberans of the neck with rapid local recurrence, satellite nodules, and a cervical lymph node metastasis, occurring simultaneously with an atypical fibroxanthoma of the scrotum. These two tumors, with distinct clinical and pathologic features, are classified as histogenetically related lesions within the spectrum of the fibrous histiocytomas. The place for the dermatofibrosarcoma protuberans at the malignant end of this spectrum is clinically and ultrastructurally documented further in our patient.
