Elastophagocytosis is the engulfment of the elastic fibres by the histiocytes, multinucleated giant cells, or both. The cutaneous lesions showing elastophagocytosis are annular elastolytic giant cell granuloma, actinic keratoses, persistent insect-bite reactions, elastosis perforans serpiginosa, foreign body granuloma. Occasionally, it may occur in infectious diseases like leprosy, granulomatous syphilis, North-American blastomycosis, bacterial folliculitis, and cutaneous leishmaniasis. We report a case of lepromatous leprosy with necrotic erythema nodosum leprosum with secondary anetoderma. Histopathology from the atrophic macule of anetoderma revealed periappendageal, perineural infiltration, elastophagocytosis and reduction in elastic fibres.
