Core Tip

Core tip: This manuscript is the first case report about tumor seeding after endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) which was surgically resected and inspected pathologically. EUS-FNA is a widely performed procedure; however, there are no clear guidelines indicating the selection of treatments in cases of tumor seeding after the procedure, as this adverse event is relatively rare. This manuscript may help in the selection of patients undergoing EUS-FNA, and clarifies the points we should be careful about after the procedure.
