Seeing double: annular diaper rash in twins.

We report a case of dichorionic, diamniotic twins who developed similar erythematous, annular, erosive plaques in the inguinal folds in the first few weeks of life that were refractory to topical antifungals and oral antibiotics. The twins were found to have high transaminase levels, antinuclear antibody positivity, and anti-SSS/Ro) and anti-SSB/La autoantibodies. The rash resolved without scarring by 7 months of age with the use of low-potency topical corticosteroids. We suggest that physicians consider neonatal lupus erythematosus in neonates with atypical eruptions occurring in sun-protected skin.
