Reticular erythematous mucinosis (REM) is a rare disorder with an unknown etiology. REM requires both a clinical and a pathological diagnosis. Multiple relevant associations and triggers are known. Herein, we report a classic case of REM, whose condition was found to be correlated with smoking and exacerbated by sun exposure. Our diagnostic and treatment approach is based on a worldwide review of current research, and this report aims to demonstrate a classical presentation of REM and available treatment options that have proved efficacious to date.
