An update on pediatric cutaneous drug eruptions.

One of the early lessons learned in dermatology training is "any drug, any rash." This maxim quickly summarizes the vast array of cutaneous reactions that can be seen in response to systemic medications. We have reviewed common and unusual drug eruptions in pediatric patients that span the morphologic spectrum. These reactions can have an equally broad range of severity, from harmless to lethal, and by the end of this paper the reader will be better equipped to sort one from the other.
