Noncancerous, Precancerous and Cancerous Tumors

Desmoplastic melanoma is a rare and invasive form of skin cancer that represents about 4 percent of all skin melanomas. The malignant cells are within the dermis and are surrounded by fibrous tissue so they may look like a scar in texture and appearance. It is usually found in older individuals who have sun damaged skin and is most often found on areas of the skin exposed to the sun such as the face, neck, scalp, legs, and arms.
