BATHING SUIT ICHTHYOSIS
By Gary M. White, MD
The autosomal recessive congenital ichthyoses (ARCI) are nonsyndromic disorders characterized by a variable degree of generalized desquamation and erythema. Most patients present at birth as a colloidion baby. Mutations in TGM1 underlie many ARCIs. Bathing suit ichthyosis (BSI) is a minor variant of ARCI characterized by skin manifestations mainly limited to the trunk.
- BSI is due to the temperature sensitivity of certain TGM1 mutations.
Patients are typically born with a collodion membrane. The rash improves, but an ichthyosis persists on the trunk, neck and scalp. There is no distribution along Blaschko lines.
