Abstract

Mucin-producing tumors of the pancreas were first reported by Ohhashi and Takagi in 1980. Since then, many cases of intraductal papillary mucinous tumor (IPMT) of the pancreas, which is almost homonymous to mucin-producing tumors of the pancreas, have been reported. IPMTs are generally regarded as tumors with a favorable prognosis. Some IPMTs have invasiveness and this is always associated with a poor prognosis. Most IPMTs arise from the main pancreatic duct and IPMTs arising from the accessory pancreatic duct are relatively rare. Only 6 cases have been reported in the literature so far. Our patient was a 43-year old man who was admitted to the hospital due to recurrent pancreatitis. An endoscopic retrograde pancreatography revealed a patulous minor papilla orifice extruding mucin and a cystic lesion in a branch of the accessory duct. A pancreaticoduodenectomy was performed and a pathologic examination of the resected specimen showed intraductal papaillary mucinous neoplasm, low grade malignancy, in the accessory pancreatic duct and its branch. We herein report this interesting case with a review of the literature.
