1/11. granular cell tumor of the biliary tree in a pediatric patient.granular cell tumor of the biliary tree is a rare benign tumor that occurs most commonly in young African-American girls. granular cell tumor rarely is included in the differential diagnosis of biliary obstruction, yet complete surgical excision is curative. The authors report a case of granular cell tumor of the biliary tree in a pediatric patient that required a pancreaticoduodenectomy for cure.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
2/11. Rabdomyosarcoma of the biliary tree.Rabdomyosarcoma of the biliary tree is one of the rare causes of biliary tract obstruction in childhood. Nevertheless it is the most common cause of obstructive jaundice due to neoplastic biliary obstruction. We present a two-year-old child with obstructive jaundice secondary to an embryonal rhabdomyosarcoma of the biliary tree. She underwent surgery and, after total excision of the mass, a hepaticojejunostomy and Roux-en-Y anastomosis were performed. She was referred to the Pediatric Oncology Group for follow-up. rhabdomyosarcoma of the bilary tree, although rare, must be considered in the etiology of obstructive jaundice in children.- - - - - - - - - - ranking = 1.1666666666667keywords = tree (Clic here for more details about this article) |
3/11. Case report: serial percutaneous cholangioscopy with laser ablation for the management of locally recurrent biliary intraductal papillary mucinous tumor.We present a case of serial cholangioscopic laser fulguration of a biliary recurrence of pancreatic intraductal papillary mucinous tumor in a 76-year-old man. Through established percutaneous biliary drain tracts, the aseptic use of a standard 6.9 F ureteroscope and holmium laser fiber facilitated visual ablation within the biliary tree. Quarterly cholangioscopic laser ablation provided safe and effective local control without biliary infectious complications. This case appears to be the first treatment of recurrent intrabiliary intraductal papillary mucinous tumor by serial antegrade choledocoscopy and laser photocoagulation. Effective local control appears possible with minimal morbidity. Standard ureteroscopic equipment facilitates safe and efficient percutaneous antegrade choledocoscopy.- - - - - - - - - - ranking = 0.16666666666667keywords = tree (Clic here for more details about this article) |
4/11. Multifocal biliary cystadenocarcinoma of the liver: CT and pathologic findings.Biliary cystadenocarcinoma is a rare tumor that originates from the hepatobiliary epithelium. Although this tumor can affect any portion of the biliary tree, intrahepatic location is more common. It is usually a slow growing tumor and often asymptomatic until it reaches a considerable size. The lesion is most often solitary and large when discovered; multiple lesions or metastases within the liver are very rare. A 63-year-old man was referred to our institute for weight loss, abdominal discomfort, worsening bulky symptoms in the right upper abdominal quadrant, and an increase in serum aminotransferases that had been present for several months. Spiral CT of the abdomen demonstrated two lesions, a larger one and a distant intrahepatic lesion, with a multiloculated cystic aspect, a thin peripheral capsule, multiple solid peripheral portions, and irregular septa enhancing in the portal phase after intravenous administration of iodinated contrast medium. The diagnosis of multifocal cystadenocarcinoma of the liver was confirmed by surgical laparoscopy and biopsy of the lesion. The patient was treated with chemotherapy.- - - - - - - - - - ranking = 0.16666666666667keywords = tree (Clic here for more details about this article) |
5/11. hemangioendothelioma of the hepatobiliary system: the classic and the unusual.Two children are reported with hemangioendothelioma of the hepatobiliary system. One patient, a 7-month-old girl, presented with classic symptomatology of hepatomegaly and congestive heart failure, but did not have any cutaneous lesions. She was treated with systemic steroids and supportive therapy and did very well. The other patient, a 22-month-old boy, is the first patient reported with exclusive involvement of the extrahepatic biliary tree. His symptoms included hepatomegaly and obstructive jaundice. He was evaluated with an endoscopic retrograde cholangiopancreatogram and a transhepatic cholangiogram. He did very well after resection of the lesion and Roux-en-Y drainage of the proximal biliary tree and remains asymptomatic 2 years after surgery.- - - - - - - - - - ranking = 0.33333333333333keywords = tree (Clic here for more details about this article) |
6/11. Cutaneous seeding of malignant tumours after insertion of percutaneous prosthesis for obstructive jaundice.Three cases of cutaneous malignant deposits at the site of skin puncture for insertion of percutaneous biliary prosthesis are described. Tumour dissemination casts doubts on the value of percutaneous intubation of the biliary tree when preparing patients for curative resection of pancreatic or biliary tumours.- - - - - - - - - - ranking = 0.16666666666667keywords = tree (Clic here for more details about this article) |
7/11. Mutagenic activity in stones from a patient with a congenital choledochal cyst.A 12-year-old boy presenting a congenital choledochal cyst complicated with stones and chronic recurrent cholangitis was subjected to surgery for cyst resection with a Roux-Y hepatojejunostomy. Potential carcinogenic factors were looked for in the cyststones using the salmonella typhimurium plate test of Ames. High mutagenic activity was found in the stone extract incubated with the TA 98 tester strain, but not with the TA 100 strain. The test was negative with stone extracts obtained from seven patients operated on for chronic gallbladder disease. This study demonstrates the presence of a mutagenic chemical in the biliary tree of a patient with a clinical condition commonly associated with biliary tract cancer.- - - - - - - - - - ranking = 0.16666666666667keywords = tree (Clic here for more details about this article) |
8/11. granular cell tumor of the biliary system.Granular cell tumors (GCT) are rare benign neoplasms of Schwann cell origin which have been found in virtually every location in the body. Their location in the biliary system is unusual, and typically occurs in black females during the fourth decade of life. Forty-eight cases have been reported since 1952. We present two patients treated for obstructive jaundice caused by GCT of the extrahepatic biliary tree. The literature on biliary GCT is reviewed and their management is outlined. Local excision with Roux-y-hepaticojejunostomy was performed in one patient with GCT obstructing the common bile duct at the level of the cystic duct. pancreaticoduodenectomy was performed on one patient for GCT of the common bile duct involving the ampulla and adjacent pancreas. GCT of the extrahepatic biliary system are rare but should be considered in black females who present with obstructive jaundice in the fourth decade of life. Local excision with cholecystectomy and reconstruction of the biliary remnant is indicated. Primary biliary anastomosis is desired but choledochojejunostomy or hepaticojejunostomy may be necessary. Rarely, pancreaticoduodenectomy may be indicated in GCT of the distal common bile duct.- - - - - - - - - - ranking = 0.16666666666667keywords = tree (Clic here for more details about this article) |
9/11. Biliary tree rhabdomyosarcoma: report of one case.A four-year-old boy was admitted due to abdominal distention for two years and jaundice of a few days duration. Abdominal ultrasound and CT scan of the abdomen showed marked dilatation of the common bile duct with two masses noted and a tumor extended to the left hepatic duct. Left hepatic lobectomy with Roux-en-Y right hepaticojejunostomy was performed which was histologically proved to be a embryonal type rhabdomyosarcoma. Chemotherapy was given postoperatively. The patient has had frequent follow-up for two years.- - - - - - - - - - ranking = 0.66666666666667keywords = tree (Clic here for more details about this article) |
10/11. Hepatobiliary rhabdomyosarcoma in children: diagnostic radiology.rhabdomyosarcoma (RMS) occurs infrequently in the liver and biliary tree. Although the radiological diagnosis may be simple when the tumour involves the extrahepatic bile ducts, no specific imaging features are known for hepatic RMS. We present four cases and discuss the role of diagnostic radiology in the management of this tumour.- - - - - - - - - - ranking = 0.16666666666667keywords = tree (Clic here for more details about this article) |
