1/73. Hepatocellular carcinoma with fibrolamellar pattern in a patient with autoimmune cholangitis.A 75-year-old woman with a 15-year history of autoimmune cholangitis underwent orthotopic liver transplantation because of progressive liver decompensation. A clinically unsuspected hepatocellular carcinoma was found. A portion of the tumor showed fibrolamellar differentiation. Hepatocellular carcinoma, either with the usual pattern or with a fibrolamellar pattern, is rare in the setting of primary biliary cirrhosis, but has been seen in the setting of autoimmune hepatitis. Autoimmune cholangitis is a relatively recently recognized form of autoimmune liver disease whose association with hepatocellular carcinoma has yet to be determined.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/73. Obstructive jaundice and acute cholangitis due to papillary stenosis.Papillary stenosis is characterized by fixed fibrosis leading to structural outflow obstruction and it is usually secondary to inflammation and fibrosis from the chronic passage of gallstones, episodes of acute pancreatitis, chronic pancreatitis, sclerosing cholangitis, peptic ulcer disease, and cholesterolosis. However, obstructive jaundice with or without acute cholangitis which leads the physician to suspect the presence of malignancy as a cause is a rare manifestation of papillary stenosis. We report here a case of papillary stenosis presenting with obstructive jaundice and acute cholangitis. The lesion was so difficult to exclude the presence of malignancy preoperatively and intraoperatively that a pylorus-preserving pancreaticoduodenectomy was performed. Histologic examination of the resected specimen revealed fibrosis, adenomatoid ductal hyperplasia, and mild chronic inflammation of the papilla of Vater and distal common bile duct.- - - - - - - - - - ranking = 0.29629105159384keywords = ductal (Clic here for more details about this article) |
3/73. Case report: two cases of biliary papillomatosis with unusual associations.Papillomatosis arising from the biliary tree is a well recognized but rare entity. We encountered two patients with this condition. However, one of them had associated hepatocellular carcinoma and cirrhosis and the other had concomitant recurrent pyogenic cholangitis. To our knowledge, these associations have not been reported before. We, therefore, present these clinical problems and highlight the added difficulty in the management of these patients.- - - - - - - - - - ranking = 0.14285714285714keywords = carcinoma (Clic here for more details about this article) |
4/73. Adenomyomatous hyperplasia of the papilla of Vater: A sequela of chronic papillitis?A case of adenomyomatous hyperplasia of the papilla of Vater is described. The lesion presented as a small polypoid tumor projecting into the duodenal lumen, causing obstruction and dilatation of the common bile duct. Serial cross-section of the ampulla showed diffuse thickening of the muscular layer corresponding to Oddi's sphincter, with resulting narrowing of the lumen. Many ductal or glandular components were dispersed within the mucosa and the muscular layer and were admixed with lymphocytes, a few lymphoid aggregates, and fibrosis. Based both on the absence of cellular atypia and the presence of inflammation, fibrosis, and preservation of the normal architecture of the ampulla, we favor the interpretation that this hyperplastic lesion represents a sequela of chronic papillitis. The different diagnoses for this lesion are presented along with a review of the literature.- - - - - - - - - - ranking = 0.29629105159384keywords = ductal (Clic here for more details about this article) |
5/73. Monolobar Caroli's disease and cholangiocarcinoma.Caroli's disease (CD) is a rare congenital disorder characterized by cystic dilatation of the intrahepatic bile ducts. This report describes a patient with cholangiocarcinoma arising in the setting of monolobar CD. In spite of detailed investigations including biliary enteric bypass and endoscopic retrograde cholangiography, the diagnosis of mucinous cholangiocarcinoma (CCA) was not made for almost one year. The presentation, diagnosis and treatment of monolobar CD and the association between monolobar CD and biliary tract cancer are discussed. Hepatic resection is the treatment of choice for monolobar CD.- - - - - - - - - - ranking = 0.85714285714286keywords = carcinoma (Clic here for more details about this article) |
6/73. Ischemic cholangitis caused by transcatheter hepatic arterial chemoembolization 10 months after resection of the extrahepatic bile duct.We report a case of ischemic cholangitis that occurred after transcatheter hepatic arterial chemoembolization (TAE). Ten months prior to TAE the patient had undergone central bisegmentectomy for hepatocellular carcinoma with resection of the extrahepatic bile duct. Eleven days after TAE, he developed suppurative cholangitis and multiple organ failure. Prior surgical ligation of the peribiliary arteries around the extrahepatic bile duct followed by TAE was considered to have played a crucial role in the development of ischemic cholangitis. This case demonstrates the importance of blood flow from the peribiliary arteries for the survival of the biliary epithelium.- - - - - - - - - - ranking = 0.14285714285714keywords = carcinoma (Clic here for more details about this article) |
7/73. Endogenous pseudomonas aeruginosa endophthalmitis: a case report and literature review.Endogenous endophthalmitis is a vision-threatening condition that results from the hematogenous spread of infection to the eye that originated in a distant primary focus. Although it has long been recognized that bloodborne organisms can infect the eye, endogenous bacterial endophthalmitis is considered a rare entity. We present a unique case of a critically ill patient with a cholangiocarcinoma complicated by ascending cholangitis who developed endogenous pseudomonas aeruginosa endophthalmitis. An awareness of the risk factors predisposing to endogenous endophthalmitis and a high clinical suspicion are necessary to make an early diagnosis in the intensive care unit. Management involves an aggressive combined medical and surgical approach in an effort to prevent ocular morbidity and vision loss.- - - - - - - - - - ranking = 0.14285714285714keywords = carcinoma (Clic here for more details about this article) |
8/73. Intrahepatic cholangitis and arteritis after transcatheter arterial embolization in a patient with tumor-like lesion-associated autoimmune hepatitis.Autoimmune hepatitis is a chronic liver disease characterized by immune-mediated, progressive hepatocellular damage, although the target autoantigen remains speculative. Intrahepatic biliary lesions are not a feature of this disease. We describe herein a female patient, 57 years, with autoimmune hepatitis who developed hepatic regenerative mass after acute exacerbation of hepatitis. This hepatic regenerative mass was clinically diagnosed as hepatocellular carcinoma and was surgically resected after transcatheter arterial embolization therapy. Widespread nonsuppurative destructive granulomatous cholangitis as well as necrotizing, granulomatous arteritis of the intrahepatic small arteries were found in the surgically resected hepatic regenerative mass. The bile duct lesions were histologically and immunohistochemically very similar to the granulomatous cholangitis of primary biliary cirrhosis. We would like to propose that these unusual lesions in the intrahepatic bile ducts and intrahepatic arteries represent a reaction of this patient to an anti-cancer drug included in chemoembolization. No such cases have been reported so far.- - - - - - - - - - ranking = 0.14285714285714keywords = carcinoma (Clic here for more details about this article) |
9/73. Periampullary choledochoduodenal fistula in ampullary carcinoma.Most patients with ampullary carcinoma have obstructive jaundice without cholangitis. We experienced a patient with ampullary carcinoma who presented with obstructive jaundice and cholangitis, probably because of an accompanying periampullary choledochoduodenal fistula. A 77-year-old Japanese man had jaundice, high fever, and upper abdominal pain and was diagnosed, at another hospital, with obstructive cholangitis. On admission to our hospital, his symptoms and signs had subsided spontaneously. Abdominal ultrasonography showed cholecystolithiasis and dilatation of the common bile duct. duodenoscopy showed an ulcerating tumor at the oral prominence of the ampulla of vater and a periampullary choledochoduodenal fistula at the bottom of the ulcer. biopsy from the fistula showed well differentiated adenocarcinoma. With a diagnosis of ampullary carcinoma with fistula formation, the patient underwent pylorus-preserving pancreatoduodenectomy. The diagnosis was confirmed by histology. This communication presents a unique case of ampullary carcinoma that caused obstructive jaundice, which subsided spontaneously but was associated with cholangitis caused by the divergent effects of the periampullary choledochoduodenal fistula formed by the carcinoma.- - - - - - - - - - ranking = 1.4285714285714keywords = carcinoma (Clic here for more details about this article) |
10/73. Bile duct cancer 25 years after choledochoduodenostomy: a case report.We describe a 65-year-old man who had undergone choledochoduodenostomy (CDS) for choledocholithiasis 25 years prior to admission to our hospital for cholangitis. Abdominal sonography and computerized tomography (CT) scan revealed a tumor mass at the hilar region with bilateral intrahepatic duct dilatation. Upper gastrointestinal endoscopic examination indicated the site of the CDS. biopsy was taken from the mucosa of the bile duct, and pathology revealed well-differentiated adenocarcinoma. CT scan and angiography further confirmed unresectable hilar bile duct cancer. Conservative treatment with intra-arterial chemotherapy was arranged. After briefly reviewing the hypothesized pathogenesis and radiographic diagnosis of this rare case, we recommend that chronic cholangitis consequent to CDS should be closely followed for late development of biliary tract malignancy.- - - - - - - - - - ranking = 0.14285714285714keywords = carcinoma (Clic here for more details about this article) |
