Recent advanced treatments for esophageal cancer may contribute to prolonging survival of esophageal cancer patients. On the other hand, a second cancer occasionally has been found in the gastric tube used as a reconstructive organ. A 75-year-old man, who had undergone curative subtotal esophagectomy with reconstruction by retrosternal gastric tube substitution for an esophageal cancer about 2 years before, was admitted to our hospital because of vomiting and sever anemia. Upon examination, carcinoma of the gastric tube was discovered. The tumor was type-1 by Borrmann's classification. A biopsy was done and pathological findings showed poorly differentiated adenocarcinoma (solid type). Consequently, total resection of the gastric tube with reconstruction by retrosternal ascending colon substitution was performed. The pathological findings revealed that the tumor was undifferentiated carcinoma. Subsequent to surgery, lung and liver metastases had developed, and these were treated with chemotherapy.

Key words
