Reticular erythematous mucinosis, A rare cutaneous mucinosis

Abstract Reticular erythematous mucinosis (REM) is a rare form of primary cutaneous mucinosis, most often involving sun exposed skin of the midline of the upper chest or back in middle-aged women. REM bears clinical and histopathologic resemblance to lupus erythematosus tumidus (LET), dermatomyositis, scleredema, and lichen myxedematosus. Early recognition and diagnosis of REM is particularly relevantas REM is more benign and has fewer systemic consequences.
