To review the dermatofibrosarcoma protuberance tumor and discuss its key radiological findings. To explain the role of radiology in the follow-up and gain awareness of skin lesions found in different imaging techniques.

When we come across a soft tissue mass identifying its origins (epidermis, dermis or hypodermis) can be of help. Also we have to consider the location within the body and the age of the patient in order to narrow down the differential diagnosis. Dermatofibrosarcoma protuberance (DFSP) is the most common mesenchymal superficial malignancy. It originates from the dermis. The peak age is between 20 and 40 years old. It affects more frequently men than woman (not in our series) and is most commonly seen on the trunk. It can recur and rarely metastasizes. We will show its key feature image on MR, CT and ultrasonography with a series obtained at our institution. We reviewed 40 cases from January 1998 until mars 2014. We found 20 males and 20 females (mean age 44 years, age range 22 to 71 years). Only 1 recurrence has been reported (9 years after the original lesion). It is important to have free margins after resections otherwise a recurrence could happen and long term follow up is needed. That is why we need to understand post treatment imaging changes and differentiate it from local recurrence.
