Acral Lentiginous Melanoma

What is acral lentiginous melanoma?

Acral lentiginous melanomas are rare and form on the palms, soles of feet and around the nail.

Acral lentiginous melanomas are most common in people with dark skin, but they can occur in any skin colour.

Symptoms of acral lentiginous melanoma:

Acral lentiginous melanoma in the nail may apppear as a streak in a nail and may damage the fingernail (not caused by an accident or injury). This can form in the finger or toenails and most often develops in the thumb or big toe. As the cancer in the nail grows, the nail may become damaged. Not all streaks in the nail are cancerous, but it’s important to contact your GP as soon as possible to get it checked.

On the palms or soles of the feet, acral lentiginous melanoma may be noticed by changes to a spot or mole. It could be an irregularly-shaped growth, that changes or is a different colour or present as a raised patch of thicker skin.


Acral lentiginous melanomas are more likely to be diagnosed at a later stage. It is important to monitor your skin and contact your GP if you notice any changes.

Remember – Acral lentiginous melanoma occurs in ALL skin colours.
