Impetigo on the buttocks: what to know

Impetigo in this area may cause itchy sores, oozing, or crusts on skin that has been rubbed, scratched, or irritated by sweat. It can be confused with insect bites, folliculitis, eczema, or irritation from products, so a diagnosis may require an examination. Because the buttocks are covered and exposed to friction, a dressing may not stay in place and the surrounding skin can become irritated.

Clean the skin gently with lukewarm water, pat it dry, and wear loose, breathable clothing. Change underwear and towels regularly, wash hands after using the bathroom or touching the rash, and avoid sharing personal fabrics. Keep nails short and avoid squeezing lesions. Do not use harsh scrubs or fragranced products on broken skin. A clinician may prescribe [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) when appropriate.

Arrange an assessment if the rash is spreading, recurring, very tender, or difficult to keep clean, or if a child has several affected areas. Seek urgent help for fever, rapidly expanding redness, severe pain, pus with worsening swelling, or marked illness. Medical [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/) may be needed when infection is extensive or deeper than the surface.

Ask whether the rash is impetigo or irritation, how to manage bathing and clothing, whether household laundry needs special handling, and when normal close contact can resume.
