A lentigo (

nevi). Because of this characteristic feature, the adjective "lentiginous" is used to describe other skin lesions that similarly proliferate linearly within the basal cell layer.[1][2]

Diagnosis

Conditions characterized by lentigines include:[3]

Differential diagnosis

Lentigines are distinguished from

freckles (ephelis) based on the proliferation of melanocytes. Freckles have a relatively normal number of melanocytes but an increased amount of melanin. A lentigo has an increased number of melanocytes. Freckles will increase in number and darkness with sunlight exposure, whereas lentigines will stay stable in their color regardless of sunlight exposure.[2]

Treatment

Lentigines by themselves are benign,[4] however one might desire the removal or treatment of some of them for cosmetic purposes. In this case they can be removed surgically,[4][5] or lightened with the use of topical depigmentation agents. Some common depigmentation agents such as azelaic acid and kojic acid seem to be inefficient in this case,[6] however other agents might work well (4% hydroquinone,[7] 5% topical cysteamine,[8] 10% topical ascorbic acid[9]).
