What should I do to get rid of the itchy red patch on my leg?

Hello,

Welcome to icliniq.com.

I have checked your attached file (attachment removed to protect the patient's identity). You gave a history of acute onset, one-week duration, and the lesion is itchy. I could see a solitary, red circular patch which is fine scaly over the patch.

The first suspect is the tinea corporis (ringworm) leg. I want to know more details about you. Kindly reply to the below-mentioned questions so that I can help you better.

1. Have you tried any topical antifungal cream or any other cream?

2. Do you have any chronic medical history like diabetes?

Lab diagnosis can be made by taking skin scrapings from the edge of the lesion, and KOH (potassium [K], oxygen [O], and hydrogen [H]) mount preparation to look under a light microscope for fungal hyphae. I would suggest you the following measures for now:

1. Skin should be kept dried and clean thoroughly.

2. Avoid close contact with anyone.

3. Do not scratch the lesion.

4. Apply topical Terbinafine 1 % cream over the lesion. Apply a thin layer of cream on the lesion twice a day for two weeks after the rash has cleared.

I hope you are not allergic to these cream ingredients. If the lesion persists after topical application of antifungal, then oral antifungal medications may be required to clear the lesion.

Please follow up if you have any further queries.
