What is the treatment for a gluteal fold rash?

Treatment of Gluteal Fold Rash

For gluteal fold rash (intertrigo), keep the area clean and dry, apply a topical corticosteroid cream (such as hydrocortisone 2.5% or triamcinolone acetonide 0.1%) twice daily, and address moisture/friction with barrier measures—if fungal infection is suspected based on satellite lesions or KOH preparation, add a topical azole antifungal. 1, 2, 3

Initial Assessment and Cleaning

• Gently clean the affected gluteal fold area with a pH-neutral synthetic detergent rather than soap, as soap can irritate inflamed skin 4, 1
• Pat the area completely dry with a soft, clean towel before applying any topical treatments 4
• Examine for signs of secondary infection: yellow crusts, discharge, painful pustules, or satellite lesions suggesting candidal involvement 4, 2

Topical Corticosteroid Therapy

• Apply a low-to-moderate potency topical corticosteroid such as hydrocortisone 2.5% or triamcinolone acetonide 0.1% cream twice daily to reduce inflammation 1, 5
• Cream formulations are preferred over ointments in skin folds, as greasy products inhibit absorption of wound exudate and promote superinfection 4
• Limit the overall duration of corticosteroid treatment to minimize risk of skin atrophy, striae, and pigmentary changes 1, 5

Management of Secondary Infection

If Fungal Infection is Suspected:

• Look for hyperpigmentation, scaling at the periphery, and satellite lesions characteristic of candidal intertrigo 2
• Perform KOH preparation to visualize yeast and pseudohyphae for definitive diagnosis 2
• Apply topical azole antifungals (clotrimazole, miconazole, ketoconazole, or econazole) in combination with the corticosteroid 2
• Reserve oral fluconazole for resistant cases or extensive involvement 2

If Bacterial Superinfection is Suspected:

• Consider swabbing the area for bacterial culture if the rash shows yellow crusts, discharge, or fails to respond to topical corticosteroids within 2 weeks 4, 5
• Initiate short-term oral antibiotics based on culture sensitivities if bacterial infection is documented 4, 5
• Do not use topical antibiotics prophylactically—reserve them only for documented superinfection 4, 2

Moisture and Friction Control

• Apply absorptive powders such as cornstarch to minimize moisture in the gluteal fold 3
• Use barrier creams or non-perfumed moisturizers containing petrolatum after the area is clean and dry 5, 3
• Consider moisture-wicking textiles within skin folds to reduce skin-on-skin friction and wick away moisture 6
• Instruct patients to wear light, nonconstricting, absorbent clothing and avoid synthetic fibers 3

Prevention of Recurrence

• Avoid skin irritants including perfumes, deodorants, alcohol-based lotions, and harsh cleansers 4, 1
• Shower after physical activity and thoroughly dry intertriginous areas 3
• Address underlying predisposing factors such as obesity, urinary incontinence, diabetes, and prolonged sitting 2, 7
• Educate patients that the gluteal fold is a weight-bearing area subjected to repeated pressure and friction, particularly in elderly or thin individuals who sit for prolonged periods 8, 9

When to Escalate Care

• If no improvement occurs after 2 weeks of topical corticosteroids and moisture control measures, evaluate for bacterial or fungal superinfection with appropriate cultures 4, 5
• Check blood granulocyte counts if systemic involvement is suspected, particularly in patients with signs of sepsis or fever 4, 5
• Refer to dermatology for persistent cases not responding to standard treatment or if alternative diagnoses (such as mucous membrane pemphigoid or senile gluteal dermatosis) are considered 8, 9

Common Pitfalls

• Avoid applying topical products immediately before activities that increase friction or moisture in the gluteal fold 4
• Do not overtreat with antiseptic creams, as this can further irritate the skin 4
• Monitor for signs of corticosteroid-induced skin thinning or telangiectasias with prolonged use 1, 5
