Primary intestinal lymphangiectasia with generalized warts

Figure 5 Histological examination of the terminal biopsy specimens. A: Hematoxylin and eosin stain (magnification × 100) showing dilated lymphatic vessels with many foamy macrophages in the lamina propria consistent with lymphangiectasia; B: CD34 stain showing normal vascular endothelial cells; C: D2-40 stained endothelial cells (red arrows), indicating dilated lymphatics; D: CD68-stained macrophages, which have aggregated to uptake lipids leaking from dilated lymphatics.
