Thank you for the information. This patch is most likely something called Granuloma Annulare. This will require a skin biopsy to prove with 100% certainty but the look is typical.

Granuloma Annulare (GA) is a skin condition characterized with the formation of granulomas in the skin. Granulomas are localized collections of certain types of white blood cells. It is not known exactly why this occurs but theories have included response to insect bites, viral infection, vaccination, and trauma among others. The condition is essentially harmless and responds well to treatment in most cases. It also often resolves on its own in many patients but its impossible to predict how long this can take. GA has many types and can occur virtually anywhere on the body.

There are several effective treatments with the first choice being potent steroid creams (e.g clobetasol, halobetasol) or intra-lesional steroid injections. Most of my patients respond to this with lesions clearing in 6-12 weeks. I would recommend seeing your GP or a dermatologist in person to get these prescription medicines as nothing over the counter will help.

Here are two excellent resource for detailed information on the condition:
