Aim White globe appearance (WGA), a small white lesion with a globular shape that can be clearly visualized by magnifying endoscopy with narrow-band imaging (ME-NBI), was reported to be a reliable marker of early gastric cancer (EGC). However, we found that this endoscopic presentation could also be seen in non-cancerous tissues, especially in ulcerative lesions. This study aimed to further investigate the diagnostic value of WGA in differentiating non-cancerous lesions from EGC in ulcer-type cases. Materials and Methods We retrospectively reviewed 54 cases of EGC and 155 cases of non-cancerous lesions in this study, all of which had endoscopic imaging data of ME-NBI scanning and pathological data of biopsy or resected specimens. The correlation of the prevalence of WGA and ulcerative lesions, as well as the characteristics of WGA between the 2 groups were analyzed in this study. Results WGA was more common in ulcerative lesions (27.6 %, 21/76) than in non-ulcerative lesions (3.8 %, 5/133) (p < 0.001) in our study. In the ulcerative cases, no significant difference in prevalence of WGA was observed between EGC and non-cancerous lesions (p = 0.532). Compared with WGA in EGC, WGA in non-cancerous lesions tended to show the characteristic of tree-branch-like vessels on globular shape (p < 0.001). Conclusions WGA is more likely to occur in ulcerative lesions, and the presence of WGA alone cannot distinguish EGC from non-cancerous lesions in ulcer-type cases. In WGA-positive tissue, tree-branch-like vessels of globular shape may provide a certain clinical value in diagnosis of non-cancerous lesions or EGC.
