In almost half of cases the ring comes back for a while, usually at the original site.
Sometimes localized lesions may respond to topical steroid ointments.

The rings vary in size from about 1/4 inch to 2 inches in diameter.

Granuloma annulare is a common skin condition with raised, flesh-colored bumps that appear in a ring.
No one knows for certain what causes granuloma annulare. I believe it is probably a slow hypersensitivity reaction that some individuals develop to different types of minor trauma. Most children with granuloma annulare are healthy and don’t go on to develop diabetes, but diabetes does occur more commonly in people who form these rings than in those who don’t.
Granuloma annulare usually disappears spontaneously within several months of appearing (though it can take years).
Other conditions that occasionally look like ringworm include seborrhea, psoriasis, pityriasis, contact dermatitis (such as poison oak), drug reactions, tinea versicolor, vitiligo, erythema migrans (a rash seen in Lyme disease), and even lupus.
Your physician can differentiate these from ringworm by a skin scraping or biopsy, if necessary.
