Serum sickness-like reactions.

Abstract

A serum sickness-like reaction (SSLR) to drug administration usually consists of cutaneous rash, arthralgia/arthritis, and, often, fever. This entity rarely has been discussed in the dermatologic literature. We describe the case of a 3-year-old girl with urticaria, fever, and arthralgia that appeared 8 days after starting cefaclor therapy for otitis media.
