 We reported the clinicopathological and endoscopic features of RSGC(raspberry-shaped gastric cancer)in patients without Helicobactor pylori infection, including their differentiation from non-neoplastic lesions. At our hospital, 24 RSGCs were endoscopically treated in 21 patients. The RSGCs were histopathologically classified into three subtypes:gastric adenocarcinoma of foveolar cells(n=19), gastric adenocarcinoma of fundic gland(n=2), and gastric adenocarcinoma of fundic gland mucosa(n=3). The endoscopic features of each subtype were reflected in the specific histopathologic findings. Therefore, an accurate diagnosis of RSGC requires the clinician to be familiar with the endoscopic and clinicopathologic features of each histological subtype.
