Cellulitis-Like Rash Associated with Kawasaki Disease.

We present the case of a 5-year-old-boy who developed a fever and cellulitis-like groin rash 5 days before developing conjunctivitis and 6 to 7 days before other typical signs of Kawasaki disease (KD) appeared. The cellulitis failed to respond to antibiotics and no pathogens were isolated. His fever and clinical signs resolved with intravenous immunoglobulin and high-dose aspirin after discontinuation of antibiotics. Nonbacterial cellulitis is a rare presenting sign of KD, but in the appropriate clinical setting and population, a diagnosis of KD should be considered when cellulitis and fever fail to respond to an appropriate antibiotic regimen and no pathogen can be isolated.
