Signs and symptoms[ edit ] Micrograph showing a palisaded granuloma in a case of granuloma annulare. Aside from the visible rash, granuloma annulare is usually asymptomatic.

Sometimes the rash may burn or itch. People with granuloma annulare usually notice a ring of small, firm bumps papules over the backs of the forearms, hands or feet, often centered on joints or knuckles.

The bumps are caused by the clustering of T cells below the skin. These papules start as very small, pimple looking bumps, which spread over time from that size to dime, quarter, half-dollar size and beyond. Occasionally, multiple rings may join into one. Rarely, granuloma annulare may appear as a firm nodule under the skin of the arms or legs. It also occurs on the sides and circumferential at the waist and without therapy can continue to be present for many years.

Outbreaks continue to develop at the edges of the aging rings. Causes[ edit ] The condition is usually seen in otherwise healthy people. Occasionally, it may be associated with diabetes or thyroid disease. At this time, no conclusive connection has been made between patients. Pathology[ edit ] Granuloma annulare microscopically consists of dermal epithelioid histiocytes around a central zone of mucin—a so-called palisaded granuloma.
