Histological sections showing lamina propria involved by a dense network of capillary-sized vascular spaces (a); immunohistochemistry was performed which shows endothelial positivity for, CD31 (b), GLUT-1 (c), and nonreactivity for D2-40 (d).

A vasoformative anomaly was present in the submucosa with involvement of the overlying mucosa where the lamina propria was occupied by a dense network of capillary-sized vascular spaces (Figure 1). Immunohistochemistry revealed that the endothelium was positive for vimentin, CD31 (Figure 1), CD34, GLUT-1 (Figure 1), and nonreactive for D2-40 (Figure 1).
