Intracholecystic papillary-tubular neoplasm of the gallbladder presenting with jaundice.
We herein report a case of intracholecystic papillary-tubular neoplasm (ICPN) of the gallbladder in which jaundice developed. A 58-year-old woman with jaundice was referred to our hospital. Computed tomography revealed a papillary tumor in the body of the gallbladder protruding into the bile duct. A transpapillary biopsy of the bile duct verified adenocarcinoma, and pancreatoduodenectomy with e...
متن کاملGallbladder papillary neoplasms share pathological features with intraductal papillary neoplasm of the bile duct
Intraductal papillary neoplasm of the bile duct (IPNB) has been widely recognized. However, the knowledge of intracystic papillary neoplasm of the gallbladder (IPNG) including papillary adenoma and adenocarcinoma is not well defined. In this study, we compared the clinicopathological and immunohistochemical features between 32 IPNG cases and 32 IPNB cases. IPNG-1 (low-high grade dysplasia) exhi...
متن کاملIntracholecystic papillary-tubular neoplasm in a patient with choledochal cyst: a link between choledochal cyst and gallbladder cancer?
BACKGROUND Intracholecystic papillary-tubular neoplasms are rare precursor lesions of gallbladder cancer. They were proposed as a separate pathologic entity in 2012 by Adsay et al. for the unification of a variety of mass-forming precursor lesions including papillary adenomas, tubulopapillary adenomas, intestinal adenomas, and others. They are considered homologous to intrapapillary mucinous ne...
متن کاملIntraductal papillary mucinous neoplasm.
A 75-year-old male with a history of dyslipidemia, no alcohol abuse, acute pericarditis and two pancreatitis episodes 16 and 3 years ago, consulted due to a new pancreatitis episode (amylase 536 IU/l). Abdominal CT and MRI showed irregular, rosary-like dilatation of the duct of Wirsung in the body and tail (Fig. 1). In the pancreatic body-tail, echoendoscopy revealed a 15-mm duct of Wirsung wit...
متن کاملIntraductal oncocytic papillary neoplasm of the pancreas: a radio-pathological case study.
CONTEXT An intraductal oncocytic papillary neoplasm is a rare pancreatic tumor with the potential of developing invasive carcinoma. Its differentiation from other cystic-like neoplasms of the pancreas, such as intraductal papillary mucinous neoplasms, is a challenge for pancreatic imaging. CASE REPORT We present the case of a 76-year-old male with painless jaundice caused by an intraductal on...
