Intraductal papillary neoplasm of the bile duct (IPNB) is a rare tumor and is considered one of the precursor lesions for cholangiocarcinoma. Though relatively common in the far east countries, it is uncommon in the Indian population. A 67-year-old gentleman presented with vague upper abdominal pain with no history of fever, jaundice, melena, or hematemesis. An abdominal ultrasound showed a solid cystic lesion in the left lobe of the liver with upstream dilatation of bile ducts. Computed tomography and magnetic resonance imaging showed similar findings. With a differential diagnosis of intrahepatic cholangiocarcinoma, intraductal papillary neoplasm, and biliary cystadenoma, he underwent robotic-assisted left hepatectomy. Histopathology was suggestive of IPNB. Following surgery, he had an uneventful recovery and was advised for follow-up visits every six months. A clinical, radiological, and pathological profile of this rare tumor has been described here with a review of the existing literature.
The purpose of this review was to analyze the most perspective methods for risk stratification of malignant transformation of pancreatic intraductal papillary mucinous neoplasms (IPMN). Advisability of humoral predictors (tumor markers, inflammatory markers, circulating leptin and branched-chain amino acids, etc.) is in identifying prognostic signs suitable for risk stratification of IPMN malignant transformation and, therefore, determining treatment strategy for a particular patient.
Background: Intraductal papillary neoplasms (IPNs) often have a similar clinical and imaging presentation, making them difficult to diagnose. We designed this study to refine and compare intraductal papillary neoplasms' clinical and imaging characteristics.
Methods: This study included a total of 154 patients with a postoperative diagnosis of IPNs and collected their clinical, imaging, and pathological data.
We report a case of solid papillary carcinoma (SPC) that developed at the site of a previous intraductal papilloma (IDP) with atypical ductal hyperplasia. This case supports IDP as a potential precursor lesion to SPC.
Background: Multiple management guidelines for intraductal papillary mucinous neoplasms (IPMNs) have been published to improve risk stratification and resource utilization. This study aims to evaluate trends in endoscopic ultrasound (EUS) use and agreement between cross-sectional imaging and EUS for specific pancreas cystic lesion (PCL) features.
Methods: This retrospective cohort study included consecutive adults undergoing EUS for suspected IPMN detected with cross-sectional imaging (CT/MRCP) between 2013 and 2015 (Cohort 1) and 2018-2020 (Cohort 2).
Background: According to previous studies, tall cell carcinoma with reversed polarity can be easily distinguished from ductal carcinoma in situ based on the absence of myoepithelium and a typical histologic feature. However, to the best of our knowledge, no cases of papillary ductal carcinoma exhibiting tall cell and reversed polarity features with intact myoepithelium have been reported, and thus its diagnosis and prognosis remain unclear.
Case Presentation: A 54-year-old female with a palpable lump in her right breast for 3 years.
