Intraductal papillary neoplasm of the bile duct (IPNB) is a variant type of the bile duct carcinoma characterized by intraductal growth. IPNB is also recognized as a precursor of invasive carcinoma. We describe herein an extremely rare case of IPNB arising from the cystic duct. A 68-year-old man was admitted to our hospital for investigation of epigastralgia and abnormal levels of biliary tract enzyme. Computed tomography and magnetic resonance imaging showed a mass lesion spreading from the cystic duct to the upper-middle bile duct. Endoscopic retrograde cholangiography demonstrated diffuse duct dilation with a grossly visible intraductal mass and amorphous blobs, suggesting the presence of mucobilia or scattered tumors. We performed extrahepatic bile duct resection with lymphadenectomy. Macroscopically, a friable papillary tumor originated from the cystic duct grows intraluminally into the bile duct. Pathologically, the tumor was found to be intramucosal adenocarcinoma spreading to the whole extrahepatic bile duct, which was compatible with IPNB. We should discuss the features and progression processes of IPNB through this precious case.

Abstract Casestudy Intraductal papillary neoplasm of the bile duct (IPNB) is a variant of bile duct carcinoma that is characterized by intraductal growth and better outcomes compared with common cholangiocarcinoma. IPNBs are mainly found in patients from Far Eastern countries, where hepatolithiasis and clonorchiasis are endemic. Approximately 40%-80% of IPNBs are associated with invasive carcinoma. The invasive carcinomas are most often tubular or mucinous type. Invasive neuroendocrine component has not been previously described. We present a case of 69 year-old African American male who presented with worsening abdominal pain and jaundice over few months. Computed tomography showed 4 cm mass near the porta hepatis with massive ductal dilatation. A fine needle aspiration of the mass was performed and a diagnosis of adenocarcinoma was made. Subsequently, the patient underwent Right Trisegmentectomy. Conclusion Histologic sections revealed intraductal papillary neoplasm in the bile duct lumina. The papillae were lined by columnar epithelial cells with delicate fibrovascular cores. The tumor cell nuclei were slightly elongated, hyperchromatic and basally located without significant multilayering. The cytoplasm was eosinophilic with occasional intestinal differentiation. Frank invasion of the stalk and underlying periductular tissues was identified. Interestingly; the invasive component had different cytological features than the intraductal component, it was composed of small to medium sized cells with granular cytoplasm. The nuclei were uniform and round with “salt and pepper” chromatin. The invasive component stained positively for the neuroendocrine markers (Synaptophysin, Chromogranin and CD56), whereas the intraductal component stained positively for CK7, CK20 and CDX2 and negative for neuroendocrine markers. Three years later, a recurrent tumor was found in the left lobe on imaging. Biopsy of the lesion showed metastatic neuroendocrine carcinoma. The intraductal papillary neoplasm with invasive neuroendocrine component is very unusual tumor, we think more studies are warranted to best evaluate the treatment options and the prognosis of such neoplasms.

Duodenum mucinous carcinoma is very rare, and the prognosis of the patient is very bad, especially when the tumor is invasive to other organs. In this case, duodenum carcinoma was invasive to common bile duct and transverse colon. Mucinous fluid, which was secreted from a duodenum tumor, was found in the dilatated bile duct. The intraductal papillary neoplasm of the bile duct was considered a differential diagnosis. We performed aggressive resection and had a good prognosis. A 74-year-old woman received a diagnosis of cholangitis and was treated with antibiotic drugs. Endoscopic retrograde cholangiopancreatography revealed a defect in the lower common bile duct with the mucoid fluid. We suspected intraductal papillary neoplasm of the bile duct, but no malignant cells were detected. One year later, gastrointestinal fiberscopy revealed a villous tumor in the postbulbar portion of the duodenum; adenocarcinoma was detected in biopsy specimens. Computed tomography revealed dilatation of the duodenum with an enhanced tumor, and dilatation of both the common and intrahepatic bile ducts. Magnetic resonance cholangiopancreatography revealed that the duodenum was connected with the common bile duct and ascending colon. We resected the segmental duodenum, extrahepatic bile duct, left lobe of liver, a partial of the transverse colon, and associated lymph nodes. Although the advanced duodenal carcinoma had poor prognosis, the patient was alive, without recurrence, 5 years after the operation.

Although there have been many previous studies of IgG4-related SC focusing on the differential diagnosis from cholangiocarcinoma, only a few patients with cholangiocarcinoma against a background of IgG4-related SC have been reported. We herein present a case of intraductal papillary neoplasm of the bile duct (IPNB) associated with invasive carcinoma complicating IgG4-related sclerosing cholangitis. A 71-year-old female with icterus was admitted to a local hospital, where stricture of the extrahepatic bile duct were detected, and subsequently referred to our hospital for possible surgery. Abdominal multidetector-row computed tomography demonstrated marked wall thickening along the entire extrahepatic bile duct. The left lateral superior bile duct (B2) and left lateral inferior duct (B3) were individually obstructed, and percutaneous transhepatic biliary drainage catheters were placed in B2 and B3 separately. The patient was diagnosed to have diffusely spread cholangiocarcinoma and underwent right hepatic trisectionectomy with caudate lobectomy and pancreatoduodenectomy. A histological examination revealed intraductal papillary tumors composed of fibrovascular stalks covered by neoplastic epithelium. Carcinomatous invasion of the papillary tumors was observed in the fibromuscular layer, and there was abundant infiltration of inflammatory cells with fibrosis outside of the cancerous tissue. The inflammatory cells were primarily composed of plasma cells, a majority of which were positive for IgG4 (>30 cells/high-power field); the postoperative serum IgG4 level was 890 mg/dL. Therefore, a diagnosis of coexisting IPNB associated with invasive carcinoma and IgG4-related sclerosing cholangitis was made. To the best of our knowledge, this is the first report of IPNB complicating IgG4-related sclerosing cholangitis.
