A 79-year-old woman with a history of invasive lobular breast cancer presented with a lesion that was endoscopically and histopathologically consistent with poorly differentiated early gastric adenocarcinoma. Endoscopic submucosal dissection was performed, and histopathological examination using additional immunohistochemistry determined that the lesion was metastatic breast cancer. Even if a lesion suspicious of gastric cancer is found on endoscopy in a patient with a history of breast cancer, the possibility of metastasis should be considered and clinicians should inform the pathologists of the possibility.
一名有浸润性小叶乳腺癌病史的79岁女性，出现了一个病变，经内镜检查和组织病理学检查，该病变与低分化早期胃腺癌一致。进行了内镜下黏膜下剥离术，通过额外的免疫组织化学进行的组织病理学检查确定该病变为转移性乳腺癌。即使在有乳腺癌病史的患者内镜检查中发现可疑胃癌病变，也应考虑转移的可能性，临床医生应告知病理学家这种可能性。
