Dermatofibrosarcoma protuberans (DFSP) is a rare type of cancer found in the dermis, the middle layer of the skin.
It is most commonly found on the torso, but can also appear on the arms, legs, heads and neck. It affects people of all ages but is most common in people aged between 20 and 50. DFSP tumours grow slowly and rarely spread to other parts of the body, but without the right treatment can grow deep into the fat , muscle and even bone making it more difficult to treat.
Surgery is the most common treatment for DFSP but in rarer cases radiotherapy and chemotherapy can also be used.
