 We analyzed clinicopathological characteristics of “Raspberry-like foveolar-type gastric adenocarcinoma” in H. pylori(Helicobacter pylori)-uninfected patients. Median patient age was 57 years(range, 38-78), and male to female ratio was 21 to 11. All lesions occurred in the upper or middle part of the stomach, and 6 patients had synchronous multiple lesions. White-light endoscopy showed a “raspberry-like appearance”, and magnification endoscopy with narrow-band imaging showed irregularly shaped papillary or gyrus-like microstructures. All lesions were determined to be intraepithelial neoplasms, however Ki-67 labeling index was high, with a median value of 62%(range, 4.4-96.5%). Multiple lesions were found more frequently than single lesion in smoking patients(83.3% vs. 34.6%, p<0.05), patients who consumed alcohol(66.6% vs. 30.7%, p=0.12), male patients(p=0.059), and in patients with fundic gland polyps(100% vs. 57.7%, p=0.59).
