Annular elastolytic giant cell granuloma: clinical case and literature review

Abstract

This entity was first described in 1975 by O’Brien, referring to it as a dermatoses characterized by papules or annular plaques, smooth borders, without scales, with a slightly atrophic hypopigmented center, postulating sun damage as the main etiopathogenic factor. He originally named it actinic granuloma (AG). Microscopically, it is seen as an infiltrate composed mainly of giant foreign body cells in relation to elastic fibers with little or no mucin, no necrobiosis or palisaded granuloma.1,2
