Drug-induced subacute cutaneous lupus erythematosus associated with omeprazole.

Subacute cutaneous lupus erythematosus (SCLE) is characterized by annular scaly erythematous plaques in a photosensitive distribution, and the presence of anti-Ro (SSA) and/or anti-La (SSB) antibodies. Most cases of SCLE are idiopathic, but occasional cases may be drug-induced or associated with a hereditary deficiency of complement components. We report two cases of drug-induced SCLE precipitated by the proton pump inhibitor, omeprazole. Drug-induced disease should be considered in all atypical or extensive cases of SCLE, especially in elderly patients. © The Author(s). CED
