Acral nevus

An acral nevus is a cutaneous condition of the palms, soles, fingers, or toes (peripheral body parts), characterized by a skin lesion that is usually macular or only slightly elevated, and may display a uniform brown or dark brown color, often with linear striations.

[1]: 1726 Acral nevi may occur in all ethnic groups, but are more common in dark-skinned people.

The prevalence of acral nevi increases directly with degree of skin pigmentation.

In a study, palmar or plantar nevi were detected in 42.0% of black (50 of 119) vs 23.0% of whites (79 of 343).

Palmar or plantar nevi of 6 mm diameter or larger were detected in 3.4% of blacks (4 of 119) vs 0.6% of whites.
