An annular erythema of infancy

An unusual annular and arciform erythema in an infant is reported. Skin lesions appeared when the child was 4 days old, and multiple lesions have been present during the subsequent two years. Individual lesions gradually enlarge over a period of a few weeks, and they resolve spontaneously without any residual cutaneous abnormality. This annular erythema is clinically and histologically distinct from previously described annular erythemas of infancy, with which it is compared.
