Annular elastolytic giant cell granuloma (AEGCG) is a controversial entity that is considered by many to be a variant of granuloma annulare (GA). The majority of cases of AEGCG occur in Caucasian women (3:2) between the ages of 40 and 70, with the distribution of the mostly annular lesions favoring exposed areas of skin and rarely involving covered skin. The most common systemic association has been with diabetes mellitus. We present a 52-year-old woman with an asymptomatic, annular, erythematous, photodistributed eruption of two-years duration. As part of her evaluation, it was detected that she had a hemoglobin A1C of 10.3% and a diagnosis of diabetes mellitus was made. We review the literature on the clinical and histopathologic features of GA and AEGCG and the overlap between these entities.
