A 64-year-old male who was found to have synchronous triple cancers following distal gastrectomy for a gastric cancer 8-years before. Endoscopic examination revealed a 0-IIb cancer in the esophagus and a IIa cancer on the suture line of the remnunt stomach. Colonoscopic examination revealed a IIa＋IIc cancer in the recto-sigmoid (Rs) . Endoscopic mucosal resection was performed for the cancers of esophagus and remnant stomach. Rs cancer was treated by laparoscopic assisted recto-sigmoidectomy with D3 dissection.
Pathohistological findings shows squamous cell carcinoma (m1, ly0, v0) in the esophageal cancer, well differentiated tubular adenocarcinoma (m, ly0, v0) in the gastric cancer and well differentiated tubular adenocarcinoma (sm3, n0, ly0, v0) in the rectal cancer. Synchronous early triple cancers of the esophagus, stomach and colon were very rare cases reported in Japan, and our case was the only one report to treat all cancers with endoscopic treatment.
