UNILATERAL LATEROTHORACIC EXANTHEM
By Gary M. White, MD
Unilateral laterothoracic exanthem (ULE), also known as asymmetric periflexural exanthem, is a not uncommon exanthema in children.
- It tends to affect young children 1-3 years of age but may rarely affect adults.
- A mild fever may be associated.
- It occasionally affects more than one family member.
- The cause is unknown but the association with Epstein-Barr virus has been noted.
A red, scaly (eczematous) or scarlatiniform rash develops on one axilla and/or flank. It may later spread to the other side, creating a symmetric distribution. It is typified by the Statue of Liberty Sign (patient raises one arm to show rash).
Clearing occurs spontaneously after 2-4 weeks. Simple use of an emollient may be prescribed. A topical steroid may be given, although it is usually not effective.
