Clinical Pearl of the Day: Granuloma Annulare
Granuloma annulare is a skin condition that causes a raised rash or bumps (lesions) in a ring pattern.
- The most common type of granuloma annulare affects young adults and usually affects the hands and feet.
- Minor skin injuries and some drugs may trigger the condition. Granuloma annulare is not contagious and usually not painful, but it can make patients feel self-conscious. If it becomes a long-term, chronic condition, granuloma annulare can cause emotional distress.
- Treatment may clear the skin gradually, but the lesions tend to come back. Untreated, the condition might last from a few weeks to decades.
- Symptoms may include localized, generalized, or under the skin.
- Causes may include animal or insect bites, infections, tuberculin skin test, vaccination, sun exposure, minor skin injuries, or drugs.
- Treatment includes corticosteroid use, ointments, creams and injections, freezing the area, light therapy, and oral medications such as antibiotics and antimalarial agents.
