Presentation
Aside from the visible rash, granuloma annulare is usually asymptomatic. Sometimes the rash may burn or itch. Patients usually notice a ring of small, firm bumps (papules) over the backs of the forearms, hands or feet, often centered around joints or knuckles. The bumps are caused by the clustering of T cells below the skin. Occasionally, multiple rings may be found. Rarely, granuloma annulare may appear as a firm nodule under the skin of the arms or legs.
