Familial annular erythema--a rare dermatology diagnosis.

We report the second case of autosomal dominant familial annular erythema since its original description in 1966 by Beare et al. A three and a half-year-old boy presented at five days of age with a widespread annular urticated erythematous rash which has persisted despite treatment with various antihistamines and mast-cell stabilizers. His mother reports an identical eruption with an absence of systemic symptoms.
