Actinic lichen planus simulating melasma

Dermatology. 1997;195(1):69-70. doi: 10.1159/000245692.

Abstract

A 23-year-old Italian woman presented with asymptomatic, symmetric, hyperpigmented patches on her face. The dermatosis became exacerbated in summer and closely resembled melasma. The histologic examination and immunofluorescence studies revealed typical features of lichen planus. Actinic lichen planus mimicking melasma is a rare dermatosis occurring mostly in women of oriental origin. The differential diagnosis of further facial melanoses will be discussed.
