Figure 1 Patient 1: colonoscopy shows a flabby potbelly-shaped pedunculated polyp (A) with a reddish and uneven head (B). The elongated polyp is composed of edematous submucosa and normal colonic mucosa (arrows), containing a depressed form of tubular adenoma (arrowheads)

Figure 2 Patient 1: the arrows indicate the tubular adenoma

Figure 3 Patient 2: colonoscopy shows an elongated polyp covered by wrinkled normal mucosa (A) with a reddish and slightly depressed surface (B). The polyp has wide areas of hyperplastic epithelium (arrows), and a well-differentiated adenocarcinoma with nonpolypoid growth (arrowheads) invades the edematous submucosa
