Figure 3 Histological and immunohistological analyses. A: Periodic Acid-Schiff staining did not reveal any collections of periodic acid-schiff positive histiocytes or inclusions, demonstrating the perfectly normal intestinal brush border (200-fold magnification); B: Immunohistochemistry for D2-40, a marker of lymphatic endothelial cells, confirms the endothelium to be of lymphatic origin and highlights the presence of multiple ecstatic lymph vessels in both the mucosa and submucosa (100-fold magnification).
