lepra cells

lep·ra cells

distinctive, large, mononuclear phagocytes (macrophages) with a foamlike cytoplasm, and also poorly staining saclike structures resulting from degeneration of such cells, observed characteristically in leprous inflammatory reactions; indistinct staining results from numerous, fairly closely packed leprosy bacilli, which are acid fast and resistant to staining by ordinary methods.
