Group with dead AWs in the PL. (a) Dilated LVs containing granulomas surrounding remains of AWs (arrows). ((b) and (c)) Rim of spindle cells positive for D2-40 compounding the granulomas (thick arrows) around remains of degenerated adult worm (thin arrows). (d) Higher magnification of the center of a filarial granuloma exhibiting D2-40 positive cells (arrows) surrounding remnant of degenerated adult worm (asterisk). (e) Small LVs at the periphery of the granulomas (arrows). (f) No cells positive for CK-7 either in surface or forming the granuloma; remnants of the worm are pointed out (arrows) ((a) HE; (b), (c), (d), (e) D2-40; and (f) CK-7. Scale bar = 50 μm).
