Treatment Options for Patch-Type Granuloma Annulare:

  1. Observation: In some cases, no treatment may be necessary, as the condition may resolve on its own.
  2. Topical Steroids: These creams or ointments can help reduce inflammation and itching.
  3. Cryotherapy: Freezing the lesions with liquid nitrogen can sometimes clear them.
