Medical Term for Diaper Rash in Adults
The medical term for diaper rash in adults is "diaper dermatitis" (DD) or "incontinence-associated dermatitis" - the same terminology used for infants, as the condition represents the same pathophysiologic process regardless of age 1, 2.
Definition and Clinical Presentation
Diaper dermatitis is an acute inflammatory reaction of the skin in the diaper-covered area, characterized by erythema, irritation, and potential erosions in the groin, perineum, and buttocks 2, 3. The condition occurs in any diaper-wearing population, which has expanded significantly to include elderly adults and those with incontinence 1.
Key Clinical Features
The presentation is identical across age groups:
- Erythema (redness) in diaper-covered areas
- Sparing of skin folds (unlike candidal intertrigo which affects folds)
- Erosions and fissures in severe cases
- Pain and discomfort with contact
Primary Subtypes
The two major forms are 3:
- Irritant contact dermatitis - Most common, caused by prolonged exposure to urine and feces
- Candida-associated diaper dermatitis - Secondary fungal infection with satellite lesions
Differential Considerations
When evaluating adults with diaper dermatitis, consider:
- Allergic contact dermatitis to diaper materials or topical products 4
- Psoriasis in the diaper area
- Seborrheic dermatitis (though this typically involves skin folds)
- Lichen sclerosus in genital areas 5
The terminology remains consistent across the lifespan - there is no separate term for adults versus infants, as the underlying pathophysiology and clinical presentation are fundamentally the same 1, 2.
