Presentation
Granuloma annulare is usually asymptomatic, but the rash may burn and be itchy. 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. T cells belong to a group of White blood cells known as Lymphocytes, and play a central role in Cell-mediated immunity. Occasionally, multiple rings may be found. Rarely, granuloma annulare may appear as a firm nodule under the skin of the arms or legs.
Prognosis
Because granuloma annulare is usually asymptomatic, treatment may not be necessary except for cosmetic reasons. Most lesions of granuloma annulare disappear in pre-pubertal patients with no treatment within two years while older patients (50+) have rings for upwards of 20 years. The appearance of new rings years later is not uncommon.
