Necrobiosis lipoidica and granuloma annulare: Part 2- Granuloma annulare

Granuloma annulare is a benign, self-limiting condition that occurs in 4% of patients with diabetes. It is usually asymptomatic; various clinical subtypes have been described, including localised, generalised, subcutaneous and perforating. The aetiology and pathogenesis is unknown, although several theories have been proposed. Numerous therapeutic strategies are documented in the literature, however, while treatment may be requested for cosmetically disfiguring or pruritic lesions, an explanation of the condition is often all that is necessary.
