What is granuloma annulare?

Granuloma annulare is a benign, chronic, inflammatory skin disease with an incompletely understood etiology. It may be related to factors such as immune responses, genetic predisposition, infections, systemic diseases, and insect bites. This condition is relatively rare clinically and commonly occurs in children and adolescents, particularly those with type 1 diabetes, as well as in young adult women. The skin lesions of granuloma annulare typically present as firm, small nodules that are skin-colored or slightly reddish, often arranged in annular or arcuate patterns. They predominantly appear on the trunk, especially the hands, feet, and joints. Lesions may gradually coalesce into plaques but typically do not cause significant itching or pain. Although granuloma annulare is self-limiting, severe or long-standing cases may require pharmacological or physical treatments to relieve symptoms. Granuloma annulare is a skin condition that requires attention and timely treatment. Patients should undergo standardized treatment under the guidance of a physician and pay attention to daily skin care and overall health management.
