Clinicopathological features and expression of regulatory mechanism of the Wnt signaling pathway in colorectal sessile serrated adenomas/polyps with different syndrome types

Figure 2 Endoscopic features. A: Adenoma in a patient with large intestine damp-heat (Da-Chang-Shi-Re) syndrome. Close observation revealed a dilated branched vessel and an open II pit; B: Polyp in a patient with spleen-stomach weakness (Pi-Wei-Xu-Ruo) syndrome. The surface was smooth, with a small amount of attached hyaline mucus. The color was similar to that of the background mucosa.
