Malignant melanoma excision wound on the back of the neck of a 76-year-old man. Melanoma is a form of skin cancer that arises from melanocytes, the cells that produce melanin, the pigment that gives skin its colour. The main cause of melanoma is exposure to ultraviolet radiation in sunlight. It is an aggressive cancer that often spreads (metastasizes) to other parts of the body. Treatment is with surgical excision of the melanoma. This is a nodular form of melanoma. For the melanoma before excision, see image C047/8461.
