  • Mucinous Cystic Neoplasms

Mucinous cystic neoplasms are the main entity to consider in the differential diagnosis of IPMN's.Two morphological features distinguish IPMN's from mucinous cystic neoplasms: IPMN's communicate with ducts, mucinous cysts do not, IPMN's also lack an ovarian stroma that is present in mucinous cysts. In addition, mucinous cysts are usually seen in the tail of the pancreas and occur in middle-aged women, while IPMN's are found in the head of the pancreas and occur in older individuals of either sex.
