Answer

Patients with localized granuloma annulare commonly present with groups of 1- to 2-mm papules that range in color from flesh-toned to erythematous, often in an annular arrangement over distal extremities. Grouped lesions may expand into arciform or annular plaques measuring 1-5 cm in diameter. Centers of lesions may be slightly hyperpigmented and depressed relative to their borders, which may be solid or composed of numerous dermal papules. Lesions most commonly manifest on the dorsal surfaces of the feet, hands, and fingers, and on the extensor aspects of the arms and legs. Rarely, lesions appear on the face, scalp, or penis.
