Аннотация
A 47-year-old man was referred to our hospital for detailed examination of a gastric polypoid lesion. Esophagogastroduodenoscopy revealed a raspberry-like polyp at the gastric body. Pathological examination of the biopsy specimen revealed this polypoid lesion to be a gastric adenocarcinoma. Endoscopic submucosal dissection was performed, and histopathological examination revealed that lesion to be a well-differentiated adenocarcinoma. Immunohistochemical staining showed that the neoplasm was positive for MUC5AC and negative for MUC6, CD10, and pepsinogen I, indicating that this lesion was a foveolar-type gastric adenocarcinoma. From about 10 years now, this patient has been undergoing esophagogastroduodenoscopy almost every year. This lesion was absent until six years ago. Five years ago, a small polypoid lesion appeared at the gastric body, and this lesion gradually enlarged. The present case showed the growing process of the foveolar-type gastric adenocarcinoma with a raspberry-like appearance.
