A 69-year-old man underwent operations due to right lung cancer in 1980, rectal cancer in 1988, and left lung metastasis from rectal cancer in 1993, respectively. In 1996, the serum CEA level started to increase in January and rose to 58.0 ng/ml by December. Abdominal CT revealed a solid tumor 1.5 cm in diameter in the pancreas located between the body and tail. Because the tumor was brighter than surrounding normal pancreatic parenchima in the abdominal angiography, it was considered a metastatic tumor. Furthermore, an ascending colon tumor was found during total colonoscopy, and it was diagnosed pathologically as moderately differentiated adenocarcinoma from the biopsy specimen. Distal pancreatectomy combined with resection of spleen and right hemicolectomy were performed with a diagnosis of metastatic pancreatic tumor and ascending colon cancer. Histological examination revealed ascending colon cancer classified mp, ly₂, v₀, n₁ (+) and pancreatic tumor metastasis from colorectal cancer. This is the sixth reported case of resection due to pancreatic metastasis from colorectal cancer in Japan. The patient is doing well without any evidence of recurrence, as of 3 years and 5 months after the operation.
