Acral lentiginous melanoma (pronunciation: ak-ral len-ti-ji-nous mel-a-no-ma) is a type of melanoma that typically occurs on the palms of the hands, soles of the feet, or under the nails. It is the most common type of melanoma in people with dark skin, but it can occur in people of all skin types.

Etymology

The term "acral" comes from the Greek word "akron," which means "extremity," and refers to the fact that this type of melanoma typically occurs on the extremities. "Lentiginous" is derived from the Latin word "lentigo," which means "freckle" or "spot," and refers to the characteristic appearance of this type of melanoma. "Melanoma" comes from the Greek words "melas" (black) and "-oma" (tumor), and refers to the fact that this type of cancer arises from melanocytes, the cells that produce the pigment melanin.
