Type of disease: Rare conditions
Scleromyxedema is a rare, severe skin disorder. Signs and symptoms include abnormal accumulation of mucin in the skin (mucinosis), causing papular and sclerodermoid bumps; increased production of fibroblasts (connective tissue cells) in the absence of a thyroid disorder; and monoclonal gammopathy (abnormal proteins in the blood). It often involves internal organs and may affect various body systems. The cause of scleromyxedema is not known. Management may involve the use of intravenous immunoglobulin (IVIG) and/or plasmapheresis, but no standard treatment exists.Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
