Acral lentiginous melanoma is a kind of lentiginous[1] skin melanoma. It is also known as subungual melanoma.
It is seen on the palms, soles and under the nails.[2] This is the most common form of melanoma in Asians and Blacks. The average age at diagnosis is between sixty and seventy years. It also occurs in Caucasians and in young people. This type of melanoma occurs on non hair-bearing surfaces of the body which may or may not be exposed to sunlight. It is also found on mucous membranes. It does not appear to be linked to sun exposure.
