What could be the cause of a red, circular and itchy patch on the leg? (photo)
My brother has a red, circular itchy patch on his leg. At times, when he scratches, it starts weeping and there is a bit of blood. What could be the cause, and could it be due to eczema?
Thank you for the question. The circular patch can go for a patch of eczema. This is often aggravated by scratching and I think it would be advisable to tell your brother to refrain from scratching. Applying moisturizers to the area also helps the eczema.
Eczema also responds well to topical steroid creams.
If the patch is persistent, you can consider visiting your doctor to get it properly assessment. A fungal scraping may be ordered to rule out a fungal infection if necessary.
This is most likely atopic dermatitis, often also called eczema. Scratching it aggravtes and prolongs the duration of the rash. It also potentially introduces bacteria into the skin and result in an infection.
Taking antihistamines helps to relieve him of the itch and reduce the scratching.
Using moisturiser helps with repairing the skin and making it stronger and less prone to breaking, which further aggravates it.
He may need some steroid cream or one combined with and antibiotic as well to reduce the rash further.
A skin scrape will help tell if is fungal in origin so that the most appropriate cream can be used.
Avoid taking hot baths or showers. Whilst doing this might help with the itch initially, the increased blood flow to the skin will make the rash worse afterwards. Try putting a wet towel in the fridge. When it itches, place the cold wet towel on the rash to relieve the rash.
Understand that stress can also trigger the rash and make it worse.
