Dermatofibrosarcoma protuberans is a rare, low- to intermediate-grade soft tissue sarcoma that is fibrohistiocytic in nature and originates from the dermis. Dermatofibrosarcoma protuberans is a locally aggressive tumour that invades deep subcutaneous tissues and has high recurrence rates. Radiological investigation is important to narrow down the differential diagnoses and to evaluate the local extent, particularly the level of infiltration of the tumour. Tumour infiltration is important for preoperative planning, especially for large tumours, as clinical examination alone may not be completely accurate and local recurrence is common, particularly for tumours with inadequately resected margins. Magnetic resonance imaging, with its superior soft tissue contrast, is particularly helpful. This report is of a patient with a large dermatofibrosarcoma protuberans on the right side of the anterior abdominal wall, and describes the radiological appearance and histopathological correlation.
