Brief Answer: Likely to be dermatitis. Detailed Answer: Hello, Thanks for posting your query. From the photos attached the most possible causes in my opinion are- 1. Erythema multiforme. 2. Dermatitis- due to skin infection, allergy,etc. 3. Dry skin- Xerosis. 4. Heat rash or due to a generalized viral infection. A direct examination by a dermatologist is the best way to get it diagnosed. Most such simple rashes improve with gentle skin care and avoiding irritating substances. You can help the improvement by * Avoid scrubbing the skin. * Use as little soap as possible. Use gentle cleansers instead. * Avoid applying cosmetic lotions or ointments directly on the rash. * Use warm (not hot) water for cleaning. XXXXXXX dry, don't rub. * Eliminate any newly added cosmetics or lotions. * Leave the affected area exposed to the air as much as possible. * Try calamine medicated lotion. * Hydrocortisone cream (1%) is available without a prescription and may soothe many rashes. The rashes usually take 5-7 days to disappear. If the rashes become more of purple rather than red then you must consult a dermatologist immediately. I hope this answers your query. In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out. Wishing you good health. Regards. Dr. Praveen Tayal.
