An intraductal papillary mucinous neoplasm (IPMN) is a benign pancreatic cyst in the ducts of your pancreas that can become malignant, or cancerous. Not all of these tumors become cancer. But researchers believe IPMNs are responsible for 20% to 30% of pancreatic cancer cases.

WebIn the intestinal-type IPMNs, MUC4/8G7 was expressed mainly in the cytoplasm of the neoplastic cells, whereas MUC4/1G8 was expressed mainly at the cell apexes. Even in the gastric-type IPMNs with rare MUC4 expression in the low-grade dysplasia, both MUC4 expression rates increased when dysplasia advanced.
