Here, we report a case of exuberant actinic granuloma annulare that, in addition to extensive scarring, showed multiple overlying open comedones. Markedly dilated follicular infundibula filled with compact masses of laminated keratinous material were observed in proximity to dermal inflammation composed of many histiocytes and multinucleated giant cells in close association with degenerated elastic fibers and abundant elastophagocytosis.engrestrictedAccessactinic granuloma annulareelastolytic giant cell granulomaelastophagocytosisgranuloma annularecomedonesarticleCopyright LIPPINCOTT WILLIAMS & WILKINSDermatology1533-0311
