Dermatofibrosarcoma Protuberans With Lymph Node and Pulmonary Metastases

Dermatofibrosarcoma protuberans is a locally aggressive histiocytic tumor that, on rare occasions, may metastasize to regional lymph nodes or even to distant sites. We report a dermatofibrosarcoma protuberans with lymph node involvement in a 27-year-old woman. This tumor recurred repeatedly after local excisions, and ten years after the first resection, widespread pulmonary metastases developed in the patient and she died four years later. More than 400 patients with dermatofibrosarcoma protuberans have been reported in the literature; including the present case, five of these patients had lymph node metastases, 17 patients had hematogenous spread, and three had both lymphatic and blood-borne metastases.
