Diaper rash is primarily an irritant contact dermatitis.
It is most common in the first 2 years of life, but can occur in a person of any age who routinely wears diapers.
Diagnosis is made by characteristic skin findings in the area of the body covered by a diaper; erythema of the convex surfaces of the buttocks is the classic finding.
Initial treatment involves reinforcing good diapering practices, such as frequent diaper changes, use of superabsorbent disposable diapers, periods of diaper-free time, and application of barrier cream, ointment, or paste.
Recalcitrant diaper rash may signal secondary infection or underlying systemic or dermatologic disorders and requires further evaluation.
Diaper rash is inflammation of the skin in the area of the body covered by a diaper. It is primarily an irritant contact dermatitis. The main irritants are urine, feces, and fecal enzymes, which lead to skin breakdown, typically of the perineum and convex surfaces of the buttocks, with sparing of the skin folds.
