Case of the Month with Crutchfield Dermatology 1 4❱❱❱❱❱ D I A G N O S T I C S BY CHARLES E. CRUTCHFIELD III, MD A 14'MONTH'OLD GIRL presents with circular red plaques on her arms and legs. They have been present for approximately three months. They do not have any scale and do not seem to change in appearance. Her mother says the plaques don't seem to bother her daughter very much, and she does not scratch them. The child's day care is concerned she has ringworm. WHAT IS YOUR DIAGNOSIS? DIAGNOSIS: ANNULAR ERYTHEMA OF INFANCY This is an odd and somewhat rare figurate erythema reported in children. It is usually asymptomatic, without overlying scale. The condition is typically constant and unchanging and can last several weeks to several months. There was an earlier report of a transient and repeating rash, but I believe this report probably represented a true urticarial variant. There is a related condi- tion — considered by some to be a variant of annular erythema of infancy — called neutrophilic figurate erythema of infancy. Dermatopathologic evaluation demonstrates a strong neutrophilic presence and karyorrhexis in these cases. Because the patient was not bothered by the eruption, I did not perform a biopsy. I informed the parents that it was not ringworm. There was neither significant scale, only mild xerosis, nor pruritus. I reassured the parents that the condition was annular erythema of infancy, and that it was a benign disease not resulting from any other health condition. It should resolve on its own over a few months. I told the parents to bring the patient in if the condition changed or became symptomatic. The mother returned to my clinic six months later for a completely di™erent skin concern of her own. At that visit the mother reported that her daughter's rash had completely cleared four months after the daughter's last visit. For more information, contact Charles E.
