Rare pancreatic neoplasms: the utility of endoscopic ultrasound-guided fine-needle aspiration—a large single center study

摘要

Background Tumors other than ductal adenocarcinomas constitute 10%–15% of all pancreatic tumors. We describe the performance and pitfalls of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for diagnosis of these rare pancreatic tumors and their characteristic cytopathological features.
