Pancreatic Adenocarcinoma With Rare Sigmoid Colon Metastasis.

Pancreatic cancer carries a poor prognosis and given insidious symptoms has often metastasized at the time of presentation. Common sites of metastasis involve liver, lungs, regional lymph nodes, or peritoneum. Colonic metastasis is rare, with only a few previous descriptions in the literature. We report a case of a 91-year-old woman with presumed pancreatic adenocarcinoma based on pathology and imaging, with colonic metastasis presenting as colonic obstruction.
