Abstract
Papulonodular mucinosis (PNM) is a rare variant of lupus erythematosus (LE) eruptions, and PNM is characterized histologically by diffuse dermal mucin without any typical epidermal inflammatory changes. We herein describe a case of papular mucinosis that was characterized by several erythematous papules on the lower back of a 32-year-old man with systemic LE. It is interesting that he didn't display any other skin manifestations of LE such as malar rash, discoid rash and photosensitivity during the previous 2 years. He achieved remission of his PNM without recurrence after 5 months treatment with topical steroids, in addition to receiving systemic antimalarials and steroids.
