A case with micro gastric cancer in the remnant stomach was reported. This 57-years-old male patient was initially operated on June 1999, because of his advanced gastric cancer with surgical type 3 at the antrum, of which histological finding was moderately differentiated adenocarcinoma with a depth of pT3 (SE) and lymph node metastasis of pN2. At 1-year-follow up on June 7th, a reddish abnormal lesion was observed at lesser curvature of remnant stomach by gastroscopy. Since the biopsy specimen revealed signet-ring cell carcinoma, he was operated on July 2000. No lesion was observed macroscopically, while the histological findings indicated the lesion of signet-ring cell carcinoma of which size was 1mm. The present case was diagnosed as a micro early gastric cancer in the remnant stomach on 1-year-after the first operation for advanced gastric cancer. Follow-up endoscopy was thought to be useful not only for the recurrence of primary cancer but also to find the secondary cancer.
