    Abstract:
    A 67-year-old woman with a pancreatic cancer diagnosed by endoscopic ultrasound with fine needle aspiration(EUS- FNA)was underwent distal pancreatectomy. Two years and 10 months after the operation, a computed tomography scan revealed a tumor in the posterior wall of the lower body of the stomach. Upper gastrointestinal endoscopy showed a 15 mm-sized submucosal tumor on the posterior wall of the angular region, and its biopsy showed tubular adenocarcinoma that it was resembling the resected pancreatic cancer. Needle tract seeding(NTS)of the pancreatic cancer to the gastric wall was suspected. After 5 courses of chemotherapy with gemcitabine and nab-paclitaxel, the tumor shrank and there were no other signs of metastasis, we performed distal gastrectomy. The pathological findings of the resected specimen showed a tubular adenocarcinoma, consistent with the primary pancreatic tumor. We finally diagnosed as the NTS of the pancreatic cancer to the gastric wall. In the case of EUS-FNA for the body or tail tumor of pancreas, it should be paid attention to the recurrence due to NTS because the surgical resection does not include the needle tract site.
