Is it eczema?
Hello: My boyfriend has a red patch on his buttocks that looks like eczema and it itches.
Since he sweats a lot, would applying baby powder help, or what should he do?
Xiao Ya, 20~29 year old female. Ask Date: 2000/11/22
Dr. Zheng Lizhen reply Dermatology
Based on your description, a possible diagnosis is tinea cruris.
Applying anti-chafing powder may help keep the area dry, but it is ineffective against the fungus itself.
Please visit a dermatologist in person for an accurate diagnosis and appropriate treatment.

More Info
When it comes to managing red, itchy skin on the buttocks, especially if it resembles eczema, it's essential to consider several factors that could contribute to the condition. Eczema, or atopic dermatitis, is a chronic inflammatory skin condition characterized by red, itchy patches that can appear anywhere on the body, including the buttocks. However, other conditions such as intertrigo (a rash that occurs in skin folds), fungal infections, or even contact dermatitis could also be responsible for the symptoms your boyfriend is experiencing.
Given that your boyfriend tends to sweat a lot, this could exacerbate skin irritation and lead to conditions like intertrigo, which occurs when skin rubs against skin and becomes inflamed, especially in warm, moist areas. The friction and moisture can create an environment conducive to fungal infections, which can also present as red, itchy patches.
Tips for Managing the Condition:
1. Keep the Area Dry: Since sweating can worsen the condition, it's crucial to keep the buttocks area dry. After showering, ensure that the area is thoroughly dried, especially in the folds of the skin. You might consider using a fan or a hairdryer on a cool setting to help with drying.
2. Use Moisture-Wicking Fabrics: Encourage your boyfriend to wear breathable, moisture-wicking underwear. Fabrics like cotton or specialized athletic wear can help reduce moisture buildup.
3. Apply Antifungal Powder: If the rash is due to moisture and friction, using a medicated powder like antifungal powder can help keep the area dry and prevent fungal growth. However, if the rash is indeed eczema, a regular talcum powder or cornstarch powder may suffice.
4. Avoid Irritating Products: Steer clear of harsh soaps, scented products, or any irritants that could exacerbate the rash. Opt for gentle, fragrance-free cleansers and moisturizers.
5. Topical Treatments: If the rash is itchy, over-the-counter hydrocortisone cream can help reduce inflammation and itching. However, if the rash persists or worsens, it’s essential to consult a healthcare provider for a proper diagnosis and treatment plan.
6. Moisturize Regularly: If the skin is dry, applying a fragrance-free moisturizer can help maintain skin hydration and barrier function. This is particularly important for eczema-prone skin.
7. Consult a Dermatologist: If the rash does not improve with home care or if it worsens, it’s crucial to seek professional medical advice. A dermatologist can provide a definitive diagnosis and may prescribe stronger topical treatments or oral medications if necessary.
Conclusion
In summary, while it is possible that your boyfriend's condition could be eczema, it is equally important to consider other potential causes such as intertrigo or fungal infections, especially given his tendency to sweat. Managing the condition involves keeping the area dry, using appropriate clothing, and applying suitable topical treatments. If symptoms persist, a visit to a dermatologist will be the best course of action to ensure proper diagnosis and treatment.
