What Causes Dry Scaly Rashes On The Upper Arm And Knee?

My 17 year old daughter has a dry scaly rash on her upper left arm and a small amount behind her left knee. We have tried lotion and it does not seem to help. There have been no changes to bath or laundry soap and she is not allergic to anything that we know of.

Hello,

The dry scaly rash on her upper left arm and small amount behind her left knee with no known allergy or changes in detergents recently is a fungal infection of the skin. A photo of the affected skin could be helpful in determining the right diagnosis.

Keep the area well clean and dry. Apply Clotrimazole lotion mixed with Hydrocortisone locally twice daily; calamine lotion during the day. If no improvement, should consult further with a dermatologist and run skin scrapping examination under the microscope.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Albana Sejdini
