What Is It?
Granuloma annulare is a harmless skin condition that forms small, firm bumps arranged in a ring or circle. The skin inside the ring usually looks normal. It's most common on the hands, feet, elbows, and knees, and it often goes away on its own over months to a couple of years.
Signs & Symptoms
-
Small, firm bumps forming a ring shape
-
Skin-colored, pink, or reddish
-
Normal-looking skin in the center of the ring
-
Usually no scale, and often no itch
-
Common on the backs of hands, feet, elbows, knees
Why Does It Happen?
The exact cause is unknown. It's thought to involve a mild immune reaction in the skin. It is sometimes linked with minor skin trauma and, in some people, with conditions like diabetes or thyroid disease, though most cases occur in otherwise healthy people. It is NOT an infection and NOT contagious.
Treatment Options
Because it's harmless and often self-resolving, treatment is optional. It's used mainly for widespread, persistent, or bothersome cases.
OBSERVATION
Often the best choice — many cases clear on their own with time.
TOPICAL STEROIDS
Creams or ointments to flatten bumps and speed clearing.
STEROID INJECTIONS
Directly into stubborn rings for a stronger local effect.
WIDESPREAD-DISEASE OPTIONS
Light therapy or other treatments for extensive cases.
