After completing training in pediatrics, dermatology, and pediatric dermatology, I am convinced that the art of medicine, especially as practiced in the field of pediatric dermatology, consists largely of an ability to use pattern recognition to separate the usual from the rare.

“Drug rash” is a common pediatric complaint in both inpatient and outpatient settings. This term, however, denotes a clinical category and is not a precise diagnosis. Proper identification and classification of drug eruptions in children are important for determining the possibility of-and preventing progression to-internal involvement. Accurate identification is also important so that patients and their parents can be counseled to avoid future problematic drug exposures.

A 1-year-old boy presented with a 10-day history of a nonpruritic rash that had persisted and spread despite treatment with a topical corticosteroid.

On day 3, his pediatrician evaluated his condition and prescribed amoxicillin for his fever and hydrocortisone cream for his atopic dermatitis. Over the next several days, the fever subsided; however, the rash, which had started on the child’s right hand, persisted and spread to his face and elsewhere.
