A Case of Submucosal Tumor-like Gastric Mucinous Adenocarcinoma Showing Mucin Waterfall / 대한소화기내시경학회지

ABSTRACT

Muinous gastric carcinoma (MGC) is a rare histological type that accounts for approximately 3~7% of all gastric carcinomas. The results of clinicopathological studies suggest that the overall survival rate for patients with MGC is worse than that for patients with non-mucinous tumors as MGC is more frequently diagnosed in the advanced stage. In this report, we preoperatively predicted the type of a tumor from its endoscopic finding. An endoscopic ultrasonographic examination showed a submucosal tumor like mass showing mucin waterfall on the gastric cardia. A total gastrectomy with splenectomy was performed. The pathology of the tumor identified the lesion as a mucinous adenocarcinoma.
