Abstract
- Scleromyxedema is a rare disorder characterized by generalized papular and sclerodermoid eruption, increased fibroblast proliferation, mucin deposition, and monoclonal gammopathy in the absence of thyroid disease. It is a generalized subtype of lichen myxedematosus. A paraproteinemia, typically an IgG lambda, is observed in more than 80% of patients with scleromyxedema. Here, we report a 38-year-old woman with a 1-year history of a progressively spreading of eruption of small papules on the entire body, including the face, neck, arms, legs, and trunk. Laboratory tests were within normal limits, except lambda light chain monoclonal gammopathy. We administered oral retinoid and topical steroid with slight clinical improvement. To our knowledge, this is the first reported case of scleromyxedema in Korea.
