Abstract

Pancreatic metastasis from colorectal cancer is rare, and there have been only a few reports of its preoperative diagnosis by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) with immunohistochemical staining. We herein describe the case of a 77-year-old woman in whom a solitary mass in the pancreatic tail was detected 11 years after rectal cancer resection. The patient also had a history of pulmonary tumor resection. We performed EUS-FNA and a histopathological examination showed adenocarcinoma with CD20+, CD7-, and CDX2+ (similar to her rectal cancer). EUS-FNA enabled a histopathological examination, including immunohistochemical staining, which helped to confirm the diagnosis of pancreatic and pulmonary metastasis from rectal cancer.
