We report a case of metachronous gastric intramural metastasis following esophageal cancer endoscopic submucosal dissection( ESD). The patient was an 80s man who was referred to the department of gastroenterology of our hospital for earlystage esophageal cancer by a local physician. ESD was performed for a lesion(Lt, 0-Ⅱa+Ⅱc, cT1N0M0, StageⅠ)located 35- 38 cm from the incisors. Pathologic diagnosis revealed that the lesion was a 2.5×2.0 cm-sized, pSM2, 506 mm, well-differentiated squamous cell carcinoma, ly+, v-, pHM0, pVM0. The patient was indicated for additional treatment, but because the patient requested not to undergo operative treatment, radiation therapy, or chemotherapy, strict follow-upwas performed. Upper endoscopy performed 1 year after ESD revealed the presence of a submucosal tumor(diameter of 5 cm)accompanied by ulceration in the gastric cardia, and biopsy findings led to the diagnosis of squamous cell carcinoma. The patient was referred to our department for operative treatment, and considering the possibility of primary squamous cell carcinoma of the stomach, we performed total gastrectomy(D2 dissection, Roux-en-Y)and cholecystectomy. The pathologic diagnosis was well-differentiated squamous cell carcinoma, ly1, v0, SE, N1. Because esophageal cancer and the tissue type were consistent and the primary locus of the tumor was the submucosal layer, the patient was diagnosed with esophageal cancer with gastric intramural metastasis. We report a rare case of metachronous gastric intramural metastasis of esophageal cancer along with a review of the literature.
