Cutaneous lupus erythematosus

Abstract

Cutaneous lupus erythematosus is a heterogeneous skin disease that is identified based on histopathological and clinical features. It can exist in the presence or absence of systemic manifestations of lupus erythematosus. Classification of cutaneous lupus into subtypes is clinically useful in predicting clinical course and potential association with systemic disease. Pathogenesis involves a genetic susceptibility and environmental triggers. An increasing number of therapeutic options are available.
