Department of Orthopaedics, General Hospital, Birmingham, UK.

A 35 year old female presented with a persistent amelanotic lesion of the nail bed of the left great toe for 1 year, associated with destruction of the overlying nail. Incision biopsy revealed a nodular malignant melanoma and the toe was amputated. There is no sign of recurrence at 18 month follow-up. As prognosis is related to local disease extent, any persistent nail bed lesion should be biopsied to exclude the possibility of malignant melanoma.

D008545	Melanoma	A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.
