Biliary papillary tumors share pathological features with intraductal papillary mucinous neoplasm of the pancreas. For a long time they were misdiagnosed as mucinous cystadenocarcinoma, ductal adenocarcinoma in situ, or chronic pancreatitis. Although intraductal papillary mucinous neoplasms are benign tumors, they can progress to pancreatic cancer. Zen Y, Fujii T, Itatsu K, et al. Although some studies report localization to the pancreatic body or tail with 2-fold increased frequency relative to the more proximal pancreas, other studies find a more uniform anatomic distribution (Table). Surgical management of patients with intraductal papillary mucinous neoplasm (IPMN) has changed since the publication of the international consensus algorithm for the management of mucinous cysts, in 2006 (Sendai guidelines). Mucinous Cystic Neoplasm (MCN) of Pancreas is an exocrine, benign or precancerous lesion, typically in the body and tail regions of the pancreas, and is characterized by the presence of mucin inside the cells (cytoplasm). Intraluminal growing, preinvasive epithelial neoplasms, such as intraductal papillary neoplasm of the bile duct (IPNB) and intraductal papillary mucinous neoplasm of the pancreas (IPMN), a precursor of invasive cholangiocarcinoma and pancreatic duct adenocarcinoma, are known to develop also in the pancreato-hepatobiliary system [1,2 Visual survey of surgical pathology with 11,460 high-quality images of benign and malignant neoplasms & related entities. Intraductal papillary neoplasm of the bile duct (IPNB), a pre-invasive neoplasm of the bile duct, is being established pathologically as a precursor lesion of invasive cholangiocarcinoma (CCA), and at the time of surgical resection, approximately half of IPNBs show stromal invasion (IPNB associated with invasive carcinoma). The sensitivity, specificity, and accuracy of cytology for the diagnosis of malignancy (high-grade dysplasia or worse) were 48.3%, 94.9%, and 84.3%, respectively. Pancreatic intraductal tubulopapillary neoplasm is genetically distinct from intraductal papillary mucinous neoplasm and ductal adenocarcinoma.
