In this book, we present a potentially recent overview of progress in cystic pancreatic tumors. We hope that this will help students to understand this pathology.Cystic tumors of the pancreas (CTPs) are a group of heterogeneous entities, constitute 2-10% of pancreatic lesions. The most common types are intracanalar papillary mucinous neoplasms (IPMN), mucocystic neoplasm (MCN) and serous cystic neoplasm (SCN), which represent about 90% of CTPs.
