Papular mucinosis, or lichen myxedematosus is one of the rare cutaneous diseases characterized by papular-lichenoid eruptions, in which mucin deposits in the dermis without thyroid dysfunction. A 31-year-old male presented with 3-5mm sized waxy, flesh-colored, multiple firm papules on the upper and lower extremities and trunk for 5 months. He did not have any familial medical history. None of the laboratory findings, including serum protein electrophoresis, was significant. Skin biopsies were performed from papules of his trunk and arm. Histopathological findings showed that the collagen fibers in the upper dermis were loosely arranged and separated by amorphous materials. These materials were all positive for alcian blue, colloidal iron, mucicarmine, and Giemsa staining. This case is compatible with discrete papular mucinosis which is the rare subtype of localized papular mucinosis.
