Is Melanosis a Cancer?
Melanosis is abnormal dark pigmentation of the skin or other tissues, resulting from a disorder of pigment metabolism. It is also called melanism. Melanism is an increased amount of black or nearly black pigmentation (as of skin, feathers, or hair) of an organism, resulting from the presence of melanin. It is the opposite of albinism, which occurs due to lack of melanin. More technically, it refers to a phenotype in which the pigmentation of an organism is entirely, or nearly entirely, expressed. A synonym for this condition used in the context of human disease is melanosis.
