Biliary tract neoplasms: diagnosis and staging
Most biliary tract neoplasms are malignant and have been traditionally divided into cancers of the gallbladder, the extrahepatic bile ducts, and ampulla of Vater. Although infrequent, bile duct carcinomas and cancer of the gallbladder are not rare. In the United States, an estimated 6000-7000 new cases of carcinoma of the gallbladder and 3000-4000 new cases of carcinoma of the bile ducts are di...
متن کاملLoss of 11p11 is a frequent and early event in sporadic nonfunctioning pancreatic neuroendocrine neoplasms
The pathogenesis of sporadic pancreatic neuroendocrine neoplasms (PNENs) is poorly understood. To gain insight into the genetic mechanisms underlying this tumor entity, we performed genome-wide screening of 16 surgical specimens from 15 patients with sporadic PNEN, combining G-band karyotyping and high resolution comparative genomic hybridization (HR-CGH). G-banding revealed abnormal karyotypes...
متن کاملCystic pancreatic neoplasms
Cystic pancreatic neoplasms are uncommon, but are being seen more frequently due to the widespread use of crosssectional imaging. In this article, we will address the clinical and imaging features of the more commonly seen neoplasms. Points of differentiation between these neoplasms, the use of cyst fluid analysis and an approach to the incidentally discovered cystic mass will be addressed.
متن کاملCystic pancreatic neoplasms.
Cystic pancreatic neoplasms comprise a heterogeneous group of pathologic entities. Mucinous cystic tumors and serous cystadenomas account for more than 75% of reported cases. While serous cystadenomas are almost uniformly benign, mucinous cystic tumors all have malignant potential and must be treated as such. While both clinical and biochemical features can distinguish among the various cystic ...
متن کاملPANCREATIC NEUROENDOCRINE NEOPLASMS (pNENs)
Pancreatic neuroendocrine neoplasms (pNENs) are relatively rare lesions that have been increasing in incidence over the past few decades largely because of the diagnosis of pancreatic incidentalomas on cross-sectional imaging. Most of these tumors are nonfunctioning presenting with symptoms secondary to mass effect, metastatic disease or as incidental findings. Diagnostic workup aims to assess ...
