Figure 4 Histopathological examination of the two cases after hematoxylin and eosin stain (at × 40 magnification for low power field images). A: Case 1 revealed a dilated submucosal cyst lined with a single layer of endothelial cells [left bottom, hematoxylin and eosin (HE) stain, × 200]; B: Case 2 displayed lymphatic vessels of varied sizes, which were covered by a flattened layer of lymphatic epithelium. The smooth muscle layer of the vessels is also noted (right bottom, HE stain, × 400).
