Dermatofibrosarcoma protuberans (DFSP) is a low grade, fibrohistiocytic malignant soft tissue tumor that arises infrequently in the foot and ankle region. It most frequently demonstrates a "storiform" histologic pattern, and if incompletely excised, may be recurrent, more anaplastic and metastatic. Soft tissue plain film radiography, as well as magnetic resonance imaging (MRI) help outline the tumor and involved tissues, which is beneficial in staging, determining surgical approach and evaluation of therapy. Definitive diagnosis is made by biopsy. A dermatofibrosarcoma protuberans is reported in the foot of a 14-year-old female patient, 4 years after trauma to the site.
