Figure 3 Histological view of the tumor revealing clusters of lymphatic vessels with a marked cystic dilatation in the submucosa and deep layer of the lamina propria mucosae. A: Staining was performed with D2-40; B: Staining was performed with hematoxylin and eosin. These characteristics are consistent with the typical features of small-bowel lymphangioma with erosions.
