A Case of Generalized Perforating Granuloma Annulare with Diabetes Mellitus / 대한피부과학회지

ABSTRACT

Generalized perforating granuloma annulare is a rare variety of granuloma annulare presenting a distinct clinical pattern. We, herein, report a case of generalized perforating granuloma annulare with diabetes mellitus, which developed on a 73 year-old-female who had pruritic generalized small papular lesions with central umbilication, especially on the back and lower extremities for 1 month. Histopathologic examination showed an epidermal perforation and transepidermal elimination of necrobiotic material. The epidermal perforation was communicated with areas of necrobiotic collagen surrounded by palisading granuloma in the dermis.
