We present a 69-year-old man with type 2 diabetes mellitus and a five-year history of an eruption of follicular pustules, papules, and nodules, which was identified histopathologically as folliculocentric granuloma annulare (GA). Folliculocentric generalized GA is a rarely reported variant of GA, in which the the palisading histiocytes form focal granulomas in a follicular pattern. In this case, the GA may represent an isotopic phenomenon, with lesions developing in hair follicles that were previously affected by a suppurative folliculitis.
