[Reticular erythematous plaques].

Reticular erythematous mucinosis (REM) syndrome primarily affects young women; the skin lesions usually appear on the chest and upper back. REM is diagnosed on the basis of the clinical picture and histological findings. REM syndrome is often associated with lupus erythematosus tumidus. Both diseases respond well to treatment with chloroquin. Topical tacrolimus and the use of a pulsed dye laser have fewer side effects and have also proved to be effective.
