title: [Pancreatic intraductal tubular carcinoma: a sub-group of intraductal papillary-mucinous tumors or a distinct entity? A case report and review of the literature].
abstract: We report the case of a 67-year-old man presenting with an isolated 3 cm mass of the pancreatic tail revealed by weight loss. Distal pancreatectomy and splenectomy were performed. Microscopically, the tumor filled the main pancreatic duct, extending into the smaller ducts and was associated with a minor adenocarcinomatous invasive component. The intraductal tumor showed a cribriform pattern, atypical cells without mucus and a MUC1+, MUC2-, MUC5AC- phenotype, all characteristics of intraductal tubular carcinoma, a new entity described by Japanese authors. The differential diagnosis and its relationship with intraductal papillary-mucinous tumors are discussed.
