AMADOR GARCIA, Raidel Aramis et al. Dermatofibrosarcoma protuberant. Presentation of a case. Rev.Med.Electrón. [online]. 2019, vol.41, n.2, pp. 530-536. ISSN 1684-1824.

Dermatofibrosarcoma protuberant (DFSP) is a rare fibrohistiocytic skin tumor of intermediate level of malignance. Locally it has an aggressive behavior extending to the subcutaneous cellular tissue and underlying muscle. Its grow is slow and painless with a high recurrence frequency after surgery. The authors present the case of a female patient operated in the Service of General Surgery of the University Hospital ¨Dr. Mario Muñoz Monroy¨ of Colon, Matanzas. Diagnosed with dermatofibrosarcoma protuberant, she arrived to the consultation with a tumor of soft tissues located in left rib cage, recidivist on a lesion resected 8 months before. It had a multinodular and irregular surface, of around 3-4 cm diameter, with bluish and dark blue areas and a reddened surrounding area of hard consistence, not adhered to deep planes. The diagnosis was ratified by the neuropathologic result. The surgical treatment was applied again with wide free-tumors margins. Metastases are rare and few frequent, but locally they can infiltrate fat, fascia, muscles and even bone structures. When they present they occur mainly in lung and regional lymphatic ganglia; in these cases survival is scarce.
