Annular Elastolytic Giant Cell Granuloma in a 53-year-old man Associated with Diabetes Mellitus

Abstract

Observation: Annular elastolytic giant cell granuloma (AEGCG), a rare granulomatous dermatosis, clinically presents as annular plaques with slightly elevated margins, and atrophic centers and histologically characterized by phagocytosis of elastic fibers by multinucleated giant cells. The pathogenesis of AEGCG has not been identified enough yet. It has been postulated that AEGCG is associated with systemic disorders such as diabetes mellitus. AEGCG is primarily observed in sunexposed areas of middle-aged women. However, some cases of AEGCG involving the regions not exposed to sun have been described. Here we report a case of a 53-year-old male patient with diabetes mellitus (DM) diagnosed as AEGCG clinically and histopathologically that has also lesions on uncovered areas as well as sun exposed areas and review the literature about this distinct entity.
