  1. Melanoma

    Melanoma is a malignant tumor of melanocytes. Melanocytes produce the dark pigment, melanin, which is responsible for the color of skin. These cells predominantly occur in skin, but are also found in other parts of the body, including the bowel and the eye. Melanoma can originate in any part of the body that contains melanocytes. Melanoma is less common than other skin cancers. However, it is much more dangerous if it is not found early. It causes the majority of deaths related to skin cancer. Worldwide, doctors diagnose about 160,000 new cases of melanoma yearly. In women, the most common site is the legs and melanomas in men are most common on the back. It is particularly common among Caucasians, especially northwestern Europeans living in sunny climates. There are high rates of incidence in Oceania, Northern America, Europe, Southern Africa, and Latin America, with a paradoxical decrease in southern Italy and Sicily. This geographic pattern reflects the primary cause, ultraviolet light exposure crossed with the amount of skin pigmentation in the population. According to a WHO report, about 48,000 melanoma related deaths occur worldwide per year.

U.S. National Library of Medicine

  1. 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. (Stedman, 25th ed; from Rook et al., Textbook of Dermatology, 4th ed, p2445)
