Abstract
Dermatofibrosarcoma protuberance (DFSP) is a relatively uncommon soft tissue tumor with intermediate-to-low grade malignancy. There is paucity of magnetic resonance imaging (MRI) and computed tomography (CT) scan literature on the appearance of DSFP. We describe the imaging findings of another rare case of DFSP in a 35 year diabetic male with progressive left arm painless swelling over seven months. CT scan and MRI were performed and reveal a mass lesion originating from the skin and embedded in the subcutaneous mass. Excisional biopsy was done and the histopathology confirmed the diagnosis DFSP.
