A benign (not cancerous) rash characterized by papules (small superficial bumps on the skin) that occur in a ring shape. The papules are frequently located on the backs of the hands and feet, or the arms and legs, of children and young adults. The rash can appear in only one spot or occur all over the body; there are usually no other symptoms. The cause of granuloma annulare is unknown.
A circular rash with a raised red border, usually found on the hands, knuckles, or arms of young patients. The cause is unknown. The rash often lasts 1 or 2 years and then may disappear spontaneously.
Tinea corporis is a benign skin condition characterized by circular, raised areas of skin that expand outward, forming ring-shaped patterns. It commonly affects children and young adults, typically appearing on the backs of their hands and feet. The exact cause of this condition remains unknown.
The diagnosis of granuloma annulare is often based on its characteristic appearance, but it can be confirmed through a skin biopsy, which involves removing a tissue sample for analysis. Generally, no treatment is required, as the skin tends to fully heal over a period of several months or years in most cases.
