Treatment:

Because granuloma annulare usually causes no symptoms, you may not need treatment except for cosmetic reasons.

Very strong steroid creams or ointments are sometimes used to clear up the rash more quickly. Injections of steroids directly into the rings may also be effective. Some health care providers may choose to freeze the bumps with liquid nitrogen.

People with severe or widespread cases may need ultraviolet light therapy or oral medications.

Expectations (prognosis):

Most granuloma annulare disappears without treatment within 2 years. Sometimes, however, the rings can remain for many years. The appearance of new rings years later is not uncommon.

Calling your health care provider:

Call your health care provider if you notice a ring anywhere on your skin that does not go away within a few weeks.
