Hello,
These itchy ringworm type lesions on the body can be due to tinea corporis or nummular dermatitis. Tinea corporis is a fungal infection of the skin which is also called ringworm and is contagious in nature. It may occur on any part of the body. Get it checked from a dermatologist as you may need KOH examination of the skin scrapings done to confirm the diagnosis.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
