A 64-year-old woman underwent an ileocecectomy in July 2002 for ruptured cecal carcinoma, which was a well-differentiated adenocarcinoma, stage II, ss, ly0, v0, n (-). In August 2005, abdominal CT revealed a tumor 20mm in diameter in the pancreatic tail, therefore, a distal pancreatectomy and splenectomy were performed. The pancreatic tumor resembled the moderately differentiated cecal adenocarcinoma, both having p53 and k-ras point mutations in common, and it was diagnosed as a metastasis of the cecal carcinoma.
