Pemphigus erythematosus: a unique association with systemic lupus erythematosus

An association between pemphigus erythematosus and systemic lupus erythematosus is well recognized. However, most reports strongly imply that the clinical manifestations of lupus erythematosus are usually minimal or only serologically significant. We describe the case of a 27-year-old black woman who experienced life-threatening systemic lupus erythematosus while recovering from pemphigus erythematosus. Unique histopathologic findings show the presence of both disorders in the same lesion.
