Nappy rash

Nappy 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 nappies.

Diagnosis is made by characteristic skin findings in the area of the body covered by a nappy; erythema of the convex surfaces of the buttocks is the classic finding.

Initial treatment involves reinforcing good nappy change practices, such as frequent nappy changes, use of super-absorbent disposable nappies, periods of nappy-free time, and application of barrier cream, ointment, or paste.

Recalcitrant nappy rash may signal secondary infection or underlying systemic or dermatological disorders, and requires further evaluation.

Nappy rash is inflammation of the skin in the area of the body covered by a nappy. It is primarily an irritant contact dermatitis. The main irritants are urine, faeces, and faecal enzymes, which lead to skin breakdown, typically of the perineum and convex surfaces of the buttocks, with sparing of the skin folds.
