RESUMEN
We report a case of a 73-year-old woman who developed pancreatic adenocarcinoma and presented with a colonic obstruction due to isolated metastasis to the colon, the primary lesion being diagnosed subsequently on imaging. The histopathological findings of the pancreatic mass exhibited a morphology and immunohistochemical profile consistent with a pancreatic adenocarcinoma and led to further analysis of the colonic pathology which ultimately confirmed the lesion was a pancreatic metastases rather than a primary colonic carcinoma. As the pancreatic cancer had metastasised to the colon, it was inoperable. The patient continued on palliative chemotherapy and passed 7 months after presentation for evaluation of her pancreatic mass due to progression of the pancreatic cancer. This report demonstrates a rare presentation of pancreatic cancer with colonic obstruction due to isolated metastatic disease and illustrated the importance of careful evaluation of histopathological findings.
