(A and B) A small gastric cancer detected by magnification endoscopy equipped with image-enhanced modalities. A small flat lesion with abnormal surface mucosal patters that is sharply demarcated by normal mucosa showing regular pit pattern. Inside the lesion, irregular, tortuous cork-screw like vessels can be identified. Alteration of mucosal surface pattern together with the presence of irregular vessels suggests early gastric cancer. Histology of the endoscopically resected specimen verified the diagnosis of gastric cancer. NBI, narrow band imaging; FICE, flexible spectral imaging colour enhancement.
