An exanthem is a widespread rash, usually of viral origin, and usually occurring in children. It represents either a reaction to a toxin produced by the organism, damage to the skin by the organism or an immune response. Exanthems may also be due to a drug, most commonly antibiotics.Historically, five "classical" childhood exanthems have been recognized: they are rubeola (measles), varicella (chicken pox), rubella, scarlet fever and "fifth disease". Roseola (aka exanthem subitum or "sixth disease") was later added to these.
A "new" exanthem was identified in 1992, unilateral laterothoracic exanthem (ULE), later also known as asymmetric periflexural exanthem of childhood.
