Presentation
Firm skin based mass.
Patient Data
A dermal based, well-defined soft tissue mass protruding from the skin of the anterolateral aspect of the left thigh and extending to the subcutaneous fat. The mass demonstrates isointense signal on T1 as compared to muscles and high signal intensity on the fluid sensitive sequences with avid enhancement in the post contrast images. The overall appearance is compatible with dermatofibrosarcoma protruberance.
Case Discussion
The case illustrates the typical location and MRI appearance of dermatofibrosarcoma protuberance. The most common location is the trunk wall followed by the proximal extremities. The mass has high local recurrence rate, therefore, multiple follow up is usually indicated.
