Overview
Diagnosis
Granuloma annulare is typically diagnosed by a healthcare provider through:
-
Physical examination: Observing the appearance of affected skin
-
Skin biopsy: A small sample of skin is taken and examined under a microscope to confirm the diagnosis
Treatment
Granuloma annulare often clears on its own, but treatment can help speed up healing. The condition may recur, usually in the same spots, though most cases resolve within two years.
Treatment options include:
-
Corticosteroid creams or ointments: Prescription-strength products may be applied directly to the skin; covering with a bandage or patch can enhance effectiveness
-
Corticosteroid injections: Used if topical treatments are insufficient; repeat injections may be given every 6 to 8 weeks
-
Freezing (cryotherapy): Liquid nitrogen can be applied to affected areas to remove bumps
-
Light therapy: Certain types of light, including lasers, may help clear the skin
-
Oral medications: For widespread cases, oral treatments such as antibiotics or antimalarial drugs may be prescribed
Treatment choice depends on the extent of the condition, symptom severity, and patient preference.
