Abstract

Gastric adenocarcinoma of the fundic gland (chief cell predominant type, GA-FG-CCP) was recently proposed as a new, rare variant of gastric adenocarcinoma. The aim of the current study was to evaluate the endoscopic features of GA-FG-CCP. A total of 10 GA-FG-CCPs were included and evaluated retrospectively. The endoscopic and clinicopathological features of the lesions were analyzed to provide information of diagnostic value. The GA-FG-CCPs were classified into two categories: submucosal tumor shape (60 %) and flat or depressed type (40 %). Endoscopically, the most common features were submucosal tumor shape (60 %), whitish color (70 %), dilated vessels with branching architecture (50 %), and background mucosa without atrophic change (90 %). GA-FG-CCP has distinct endoscopic characteristics, especially in terms of shape, color, vessels, and background mucosa and may be classified into two categories macroscopically. To diagnose GA-FG-CCP correctly by pathological examination of biopsy specimens, these endoscopic features should be taken into consideration.
