Abstract
The patient was a 62-year-old man, with a history of gastrectomy for gastric cancer (signet ring cell carcinoma) in 1991. He was admitted for ileus in April, 1999. He received a right hemicolectomy with combined resection of the liver, gallbladder and abdominal wall because of tumor invasion in the transverse colon near the hepatic flexure. Pathological findings showed that the tumor existed mainly in the extramural part of the colon and that the histological type was signet ring cell carcinoma. Operations were performed for ileus in October, 2000, and again in February, 2003. Peritoneal dissemination of the small intestine and the peritoneum were resected as much as possible. Whole specimens showed signet ring cell carcinoma. The patient underwent chemotherapy after the operation. There has been no recurrence for more than 10 years since the last operation, and he is followed at present. In this case, peritoneal recurrence of gastric cancer was suspected because every specimen, like the primary lesion, showed signet ring cell carcinoma, gastric mucin type and cytokeratin 7(+) , 20(–). We report an unusual course of gastric cancer with a review of the literature.
