Hello, thank you for the photo and question. From your picture, the most likely diagnosis is that you have lichen simplex chronicus, a localised patch of eczema due to repeated rubbing and scratching. This can be successfully treated with potent topical steroids.
Oral tablets can be given to relieve your itch if necessary.
There are also other causes for the appearance of your rash, and a good history and examination with a dermatologist will usually give a clear diagnosis and the appropriate treatment can be advised. Hope this helps!
Best regards
Dr Stephanie Ho, Dermatologist
