Melanotic lupus erythematosus: A rare variant of discoid lupus erythematosus

Discoid lupus erythematosus (DLE) is characterized by atrophic patches with peripheral hyperpigmentation on sun exposed skin areas. It rarely presents with diffuse hyperpigmented patches without erythema, adherent scale and atrophy on face and neck. This presentation is called as melanotic lupus erythematosus and it is rarely reported in literature. Other diseases that cause facial pigmentation as melasma, Riehl melanosis, lichen planus pigmentosus, drug related pigmentation should be considered in the differential diagnosis. We herein report a 66 year old male patient with diffuse blue-brown pigmentations on his face which was diagnosed as melanotic lupus erythematosus with the clinical, histopathological and immunofluoresence findings.
