Estudio Observacional: Dermatofibrosarcoma Protuberans, Serie de casos.

Introduction: Dermatofibrosarcoma protuberans (DFSP) is one of the rare tumors found in the fibrohistocytic sarcomas and it is characterized by slow and progressive growth. Methods: A retrospective study of six cases treated at the Skin Center (CEPI) between 2010 and 2019 was carried out. We have take into account demographic information, characteristics, treatment and evolution of the lesions. Results: Six patients were diagnosed and treated by DFSP. There was a predominance of women (4 women, 2 men) with a mean age of 58.2 (SD = 19.6), three of them presented lesions in the form of indurated plaque and the rest presented a unique nodule. The locations of the lesions were the shoulder, neck and hypogastrium. The most commonly used treatment was wide excision, none of the patients presented recurrences at the first and fifth year of follow-up. Conclusion: Recognition of the typical clinical characteristics of DFSP is necessary since it could be mistaken as a benign tumor of the skin. The diagnosis must be always done by histopathological confirmation.
