El dermatofibrosarcoma protuberante es un raro tumor fibrohistiocitario de la piel y grado intermedio de malignidad. Localmente tiene un comportamiento agresivo, se extiende al tejido celular subcutáneo y músculo subyacente. Su crecimiento es lento e indoloro con una alta frecuencia de recurrencia posterior a la intervención quirúrgica. Se presentó una paciente operada en el Servicio de Cirugía General del “Hospital Universitario Dr. Mario Muñoz Monroy” de Colón, Matanzas. Diagnosticada con dermatofibrosarcoma protuberans se presentó con un tumor de partes blandas, localizado en parrilla costal izquierdo, recidivante sobre una lesión resecada anteriormente hacia 8 meses. El tumor de superficie multinodular e irregular, de aproximadamente 3 a 4 cm de diámetro, presentaba zonas de color azuladas y otras más oscuras con un área enrojecida circundante, consistencia dura, y no adherida a planos profundos. Con el resultado anatomopatológico se ratificó el diagnóstico. Nuevamente se aplicó tratamiento quirúrgico con amplios márgenes libres de tumor. Las metástasis son raras y pocos frecuentes, pero localmente pueden infiltrar, grasa, fascia, músculos y hasta estructuras óseas. Cuando se presentan ocurren generalmente en pulmón y ganglios linfáticos regionales, en estos casos la supervivencia es muy poca.

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.
