Acral lentiginous melanoma (ALM), occurring on the hands and feet (palms, soles, fingers, toes, and nail units) was first defined as a distinct subtype of cutaneous melanoma (CM) by Arrington et al. (1977). It is the least common subtype of CM comprising only about 2.5% of total melanoma diagnoses in Caucasians.

What causes acral melanomas?

What is the cause of acral lentiginous melanoma? Acral lentiginous melanoma is due to the development of malignant pigment cells (melanocytes) along the basal layer of the epidermis. These cells may arise from an existing melanocytic naevus or more often from previously normal-appearing skin.

Is acral melanoma rare?

Acral lentiginous melanoma is a very rare type of skin cancer, and it affects people with darker skin more than any other demographic. Other types of melanoma are caused by sun exposure that damages your skin.
