Chylocele. (a) PL thickened with numerous granulomas (arrows) surrounding spindle-shaped clefts of cholesterol crystals. (b) Granulomas with foreign-body giant cells (arrows) encasing cholesterol crystals (the cholesterol disappeared during tissue processing, leaving an empty cleft). (c) Disperse immunoreactivity for D2-40 in areas rich granulomas (arrows). (d) Spindle cells stained by D2-40 (arrows). (e) Microvessels stained by D2-40 (arrows) with diameters varying from 3.6 μm to 5.7 μm (mean, 4.5 μm). The giant cells (thick arrow) are negative for D2-40. (f) MCs (arrows) located at different levels ((a), (b) HE; (c), (d), (e) D2-40; and (f) CK-7. Scale bar = 50 μm).
