A 66-year-old man underwent a single endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) session and distal pancreatectomy for the pancreatic body adenocarcinoma measuring 12 mm in diameter. At 3 years after surgery, we diagnosed needle tract seeding (NTS) and performed total gastrectomy. NTS can occur with small tumors or after a single session of EUS-FNA.
