Granuloma Annulare

This condition normally affects the back of the hands, the top of the foot, elbows and knees. It can also spread out along the arms and up the legs and even to the buttocks.

Twice as many women are affected and it usually presents in childhood or in young adults.

This condition is a benign, uncommon, slow progressing skin condition of unknown causes. It initially presents as small red or purple papule or papules that slowly develop into an irregular “ring” of firm papules that can be 0.5 to 5 cm in diameter.

Granuloma annulare is often misdiagnosed as tinea (ring worm) because of the round pattern. It is important to note that unlike tinea, where the border usually presents with scaling, the border of granuloma annulare does not present with a scale and is usually a raised, smooth leading edge.

It can last for months or years, however, in 75% of patients it will resolve within 2 years. Recurrences are common.
