A case of lupus erythematosus/lichen planus overlap syndrome (LE/LP overlap syndrome) was reported. A 53-year-old woman developed violaceous erythema around the nostrils and the upper lips and atrophic scaly erythema on the cheeks and neck. Histopathological studies revealed that the patient had distinct discoid lupus erythematosus (DLE), LP, and a lesion with combined features of DLE and LP. Direct immunofluorescent (DIF) studies of the mixed lesion revealed both prominent immunoglobulin (Ig)G deposits in a granular pattern at the basement membrane zone (BMZ) and IgM deposits in the clusters of cytoid bodies; the former are more typical of LE and the latter more of LP. DIF features in combination were unique for LE/LP overlap syndrome. The patient was satisfactorily treated with topical tacrolimus. While reports support the effectiveness of tacrolimus in either LE or LP, this is the first case of LE/LP overlap syndrome treated with topical tacrolimus.
