초록
Gastric cancers that fulfill the Japanese criteria for curative endoscopic resection show a low risk of lymph node (LN) metastasis. Here,we report a case of LN metastasis from early gastric cancer that fulfilled the curative criteria. A 74-year-old Japanese woman wasreferred to our hospital for treatment of early gastric cancer identified at the site of a hyperplastic polyp that had been diagnosed 10years prior to presentation. Contrast-enhanced computed tomography did not show any lymphadenopathy and laparoscopy-assisteddistal gastrectomy was performed. Histopathological examination revealed a predominantly moderately differentiated adenocarcinomathat measured 15 mm in size and was confined to the mucosa. However, a single metastatic regional LN was observed. A few cancercells showed positive staining for alpha-fetoprotein. It should be noted that early gastric cancer can be accompanied by LN metastasiseven if it fulfills the criteria for curative endoscopic resection.
