Granuloma Annulare

Granuloma annulare is a benign, self-limited dermatosis characterized by a raised annular distribution (Fig. 33-35). The condition may be localized, generalized, perforating, or subcutaneous. Except for subcutaneous granuloma annu-lare, the subtypes have similar appearances, but each follows a distinct clinical course. Subcutaneous granuloma annulare appears differently, with deep dermal or subcutaneous nodules. Patients with localized granuloma annulare present with groups of 1-mm to 2-mm papules in an annular arrangement over the distal extremities, ranging in color from skin tone to erythematous. Lesions most frequently appear on the dorsal surfaces of the hands and feet, fingers, and extensor aspects of the arms and legs. In generalized granuloma annulare, patients have a few to thousands of papules and rings that involve many body regions. The rings tend to be distributed symmetrically. Patients with perforating granuloma annulare present with up to hundreds of grouped 1-mm to 4-mm papules that may evolve into pustular lesions that drain and umbilicate, leaving atrophic scars. These lesions tend to appear on the extensor surfaces of extremities and the dorsa of the hands and fingers. Granuloma annulare may resolve spontaneously but can take several years. When patients request treatment, steroid injections are most effective.
