This is a 34-yr-old male with a history of scalp lumps. Is this a case of…
Lipoma?
Dermatofibrosarcoma? or
Sebaceous Cyst?
Correct Answer
Dermatofibrosarcoma Protuberans. This is a rare neoplasm of the dermis layer of the skin, and is classified as a sarcoma. It usually occurs in the trunk or extremities but can involve the head and neck particularly the scalp. In many respects, the disease behaves as a benign tumour, but in 2%-to-5% of cases it can metastasize, so it should be considered to have malignant potential.
