Main-duct intraductal papillary mucinous adenoma of the pancreas

BACKGROUND: The prevalence of carcinoma in main-duct intraductal papillary mucinous neoplasm (IPMN) is high, and surgical resection is recommended for all patients with a main-duct IPMN. RESULTS: A main-duct IPMN with typical imagings including protruding lesions in the dilated main pancreatic duct...

Sumario:BACKGROUND: The prevalence of carcinoma in main-duct intraductal papillary mucinous neoplasm (IPMN) is high, and surgical resection is recommended for all patients with a main-duct IPMN. RESULTS: A main-duct IPMN with typical imagings including protruding lesions in the dilated main pancreatic duct was resected, but the histology was intraductal papillary mucinous adenoma of the pancreas. DISCUSSION: It has been reported that the presence of mural nodules and dilatation of MPD are significantly higher in malignant IPMNs. The presented case had protruding lesions in the dilated main pancreatic duct on endoscopic ultrasonography, but the histology was adenoma. CONCLUSION: Preoperative distinction between benign and malignant IPMNs is difficult.
