Localized granuloma annulare
Localized granuloma annulare (pronunciation: loh-kuh-lized grah-noo-loh-muh an-yuh-lair) is a type of skin disorder that is characterized by the appearance of small, firm bumps (nodules) over the skin. The exact etymology of the term is not known, but it is derived from the Latin words 'granulum' meaning 'small grain' and 'annulare' meaning 'ring-shaped'.
Definition
Localized granuloma annulare is a benign, self-limiting skin condition that typically presents as ring-shaped plaques. It is the most common form of granuloma annulare, a condition characterized by raised, reddish or skin-colored lesions that form ring patterns, usually on the hands and feet.
Symptoms
The primary symptom of localized granuloma annulare is the presence of small, firm, skin-colored or red bumps that appear in ring patterns. These bumps, or lesions, are usually found on the hands, feet, wrists, and ankles. Other symptoms may include mild itching.
Causes
The exact cause of localized granuloma annulare is unknown. However, it is thought to be related to certain triggers such as minor skin injuries, insect bites, or vaccinations. It is not contagious and does not spread from person to person.
Treatment
Treatment for localized granuloma annulare is not usually necessary as the condition often resolves on its own. However, if the lesions are bothersome, treatments such as corticosteroid creams or ointments, light therapy, or oral medications may be used.
