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]).
