Acral melanoma, sometimes called acral lentiginous melanoma, is a rare type of skin melanoma that forms on the palms, soles of feet, or under finger or toe nails. Acral melanoma is the most common type of melanoma among people with darker skin.
Unlike cutaneous, acral melanoma is not believed to be caused by exposure to the sun or other sources of ultraviolet radiation.
Acral melanoma begins as a patch of discolored skin that gets bigger over time.
When caught early, acral melanoma can be easily treated. Learn more about treatment options for acral melanoma.
