Dermatofibrosarcoma protuberans of the breast: a case report

Dermatofibrosarcoma protuberans (DFSP) is an uncommon mesenchymal tumour of the dermis and subcutis, which most commonly appears on the body and the extremities. Its occurrence in the breast is rare, and when it does, it can mimic a primary, benign breast lesion. We present a case of DFSP over the breast of a patient together with the associated imaging findings that can potentially help us differentiate this tumour from a primary breast lesion. The awareness of this entity allows a prompt diagnosis to be made and the disease to be properly managed.
