    Abstract:
    A woman in her 80s was diagnosed with pancreatic tail cancer by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). We performed laparoscopic distal pancreatectomy followed by adjuvant chemotherapy with S-1 for 6 months. One year after surgery, contrast-enhanced computed tomography revealed a 15 mm mass in the posterior wall of the gastric body. EUS showed a hypoechoic mass in the muscular layer in the gastric wall, which was diagnosed as adenocarcinoma by FNA. We diagnosed gastric wall recurrence due to needle tract seeding(NTS)following EUS-FNA and performed partial gastrectomy. Histopathological diagnosis was gastric wall recurrence of pancreatic cancer. Since NTS following EUS-FNA can be proven only by the presence of gastric wall recurrence after surgery for pancreatic body or tail cancer, the actual risk of NTS including peritoneal dissemination is not clear and may have been underestimated. In case of resectable pancreatic body or tail cancer, indication for EUS-FNA should be carefully considered.
