Streptococcal intertrigo: an underrecognized condition in children.

Group A beta-hemolytic streptococci have been implicated in a variety of common childhood cutaneous infections. Infants and young children may be particularly susceptible to a form of streptococcal intertrigo that has heretofore been underrecognized in this population. Manifesting as intense, fiery-red erythema and maceration in the intertriginous folds of the neck, axillae, or inguinal spaces, the condition is characterized by a distinctive foul odor and an absence of satellite lesions. Specific clinical features help differentiate this condition from its clinical mimics. Topical and oral antibiotic therapy with or without concomitant low-potency topical steroid application is generally curative.
