Understanding Scabs in the Buttocks: Causes & Remedies

Scabs in the intergluteal cleft ("butt crack") have diverse causes:

1. Anal fissures: Tears from hard stool/straining → bleeding, scabbing
2. Hemorrhoids: Thrombosed or ruptured external hemorrhoids
3. Infections: Bacterial (impetigo), fungal (tinea, Candida), viral (HSV)
4. Trauma: Friction, scratching, hygiene practices
5. Inflammatory dermatoses: Psoriasis (inverse), lichen sclerosus, seborrheic dermatitis
6. Benign growths: Seborrheic keratoses (can irritate, bleed)
7. Pilonidal cyst/sinus: Chronic infection near coccyx

When to See a Doctor

• Persistent >2 weeks
• Pain, bleeding, drainage
• Spreading redness, fever
• Change in bowel habits
• History of IBD, immunosuppression

Treatment targets cause: stool softeners (fissures), antifungals/antibiotics, topical steroids (inflammatory), excision (pilonidal, keratoses).
