Erythroderma

Erythroderma is an inflammatory skin disease in which redness and scaling spread across nearly the whole surface of the skin. The term is used when ninety percent or more of the skin is affected, which separates it from ordinary patchy rashes that cover only part of the body. It is a description of a pattern of skin involvement and not a single disease with one cause, so it is recorded in clinical practice alongside whatever underlying condition produces it. The international disease classification treats the picture in two places: ICD-10 lists exfoliative dermatitis at code L26 and erythroderma at code L53.9, and draws a distinction between the two. The source article used here is brief, so this entry states only the definition and the coding, and does not list causes or treatments. This entry is a record of what the source holds and is not medical advice.
