Abstract
A 75-year-old male patient underwent laparoscopic-assisted low anterior resection of the rectum with D3 lymph node dissection. The pathological diagnosis was papillary adenocarcinoma (se, ly0, v2, N0, P0, H0, M0, Stage II). He also underwent right pulmonary surgery for right pulmonary metastasis, and left adrenalectomy for left adrenal metastasis 18 months and 33 months after the primary surgery, respectively. During his follow up, computed tomography scan revealed a tumor 3cm in size in the head of the pancreas 56 months after the primary surgery. After several detailed examinations, with a diagnosis of pancreatic metastasis from the rectal cancer, a pancreaticoduodenectomy was performed 58 months after the initial surgery. The pathological diagnosis was the metastasis to the pancreas from the rectal cancer, because tumor cells were immunohistochemically negative for cytokeratin 7 and positive for cytokeratin 20. There has been no indication of recurrence for 21 months after the pancreatic surgery. Resectable pancreatic metastasis from colorectal cancer is rare, but pancreatic resection may achieve long-term survival in some cases. We present this case with a review of the literature.
