สรุป

• 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 re-enforcing 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.
