Supra-elevated CA 19-9 in a benign hepatic cyst adenoma.

Background: Elevated CA 19-9 may be found in both cystadenomas and cystadenocarcinomas of the liver.

Case Outline: A 59-year-old woman presented with right upper quadrant abdominal pain, malaise and weight loss. Physical examination and laboratory evaluation revealed a mass in the right upper quadrant and a CA 19-9 level of 68 661 U/ml.

Biliary cystadenoma revealed by obstructive jaundice.

Biliary cystadenoma is a rare cystic tumour of the liver that can be difficult to differentiate from other types of benign hepatic cysts. We report the case of a 32-year-old woman who presented with obstructive jaundice due to a large cystic lesion of the left hepatic lobe. Resection of the mass revealed a mucinous cystadenoma with protrusion of a pedunculated extension into the left hepatic duct and the common bile duct.

Intrahepatic biliary cystadenoma: a need for radical resection.

Background: Intrahepatic biliary cystadenoma (IBC) is a rare liver tumour, which has strong tendency to recur and malignant potential as it can progress to cystadenocarcinoma (IBCa).

Methods: From June 2003 to December 2006, four patients diagnosed with hepatic cystadenoma were operated on our Liver Surgical Unit. All patients were females with median age of 51 years (range 45-63 years).

Malignant histiocytosis with central nervous system involvement and hepatic mucinous cystadenoma in a single patient with review of the literature.

Malignant histiocytosis is a rare neoplasm of the reticuloendothelial system characterized by neoplastic proliferation of tissue histiocytes. We report a case of malignant histiocytosis in a 64-year-old female initially operated on for a mucinous cystadenoma of her liver. Four months after the operation, skin induration on the neck and anterior thoracic wall and systemic lymphadenopathy were noted.

[Biliary cystadenoma with mesenchymal stroma].

The data available in the literature and the authors' observation of hepatic adenoma polycysticum developed in a 34-year-old female are given. A comprehensive morphological (histological and immunohistochemical) study has shown that the cystic wall is lined with the cylindrical epithelium that has a positive reaction with cytokeratins 7, 18, 19, and 20, CA 19-9. The underlining tissue resembles ovarian tissue and positively reacts with vimentin, estrogen, and progesterone.

[Imaging of cystic liver diseases].

The high frequency of benign and asymptomatic liver cysts must not underevaluate the potential diagnostic difficulties of liver cystic diseases. Complicated liver cyst or cystic mass of various origin, such as developmental, neoplastic or inflammatory, are important to be recognized by the radiologist. The diagnostic approach is depending on the number of lesions and their dissemination.

[Littoral cell angioma of spleen: a clinicopathologic study of 17 cases].

Objective: To study the clinicopathologic features and immunophenotype of splenic littoral cell angioma.

Methods: The clinical features, radiologic findings and histopathology of 17 cases of splenic littoral cell angioma were retrospectively reviewed. Immunohistochemical study was carried out on paraffin-embedded tissues, using normal spleen, cases of congestive splenomegaly and cavernous hemangioma as controls.

The rare benign liver tumors.

As opposed to malignant secondary tumors, metastases of the colorectal carcinoma are benign tumors of the liver that are quite rare in the Czech Republic. From the 55 patients operated on since 2000 at our department for benign liver tumors, the most frequent are haemangiomas, focal nodular hyperplasia (FNH) and hepatocelular adenoma. Only 7.

Expression of estrogen and progesterone receptors and inhibin-alpha in hepatobiliary cystadenoma: an immunohistochemical study.

To further characterize the immunohistochemical features of hepatobiliary cystadenoma with mesenchymal stroma, a battery of stains was performed on nine typical cases. All nine tumors had been resected from female patients who ranged in age from 30 to 59 years. Freshly cut sections were stained with antibodies to estrogen receptor (ER), progesterone receptor (PR), alpha-smooth muscle actin (SMA), inhibin-alpha, and cytokeratins (CK) 7, 8, 18, and 19.

[The "inspection jejunostomy" after complex reconstructions of the central bile ducts].

Introduction: Hutson and Russell described in 1984 a surgical technique, where a modified Roux-en-Y hepaticojejunostomy with the afferent limb brought up as jejunostomy after complex reconstructions of the central bile duct was performed [4]. It facilitates endoscopic retrograde access to the biliary tree for control examinations and biopsies in complicated reconstructive procedures after bile duct resection. We report our experience with this operative procedure.

Biliary cystadenoma of the left intrahepatic duct (2007: 2b).

Biliary cystadenoma is a rare epithelial cystic neoplasm representing only 5% of intrahepatic cystic lesions of biliary origin. Commonly, the lesions are solitary cystic structures with multiple thin-walled septa predominantly arising from the right hepatic duct. Although the lesions are generally intrahepatic, extrahepatic tumors have been reported.

Giant mucinous biliary cystadenoma: a case report.

Background: Biliary cystadenoma is a very rare cystic neoplasm of the liver. Its clinical features, diagnosis, pathologic characteristics, and optimal surgical management have not been defined clearly. In this article we describe the details of this rare disease.

Hepatic von Meyenburg complex simulating biliary cystadenocarcinoma.

Multiple bile duct hamartomas [von Meyenburg complex (VMC)] are benign liver malformations that include biliary cystic lesions, with congenital hepatic fibrosis being the cause of ductal plate malformations. This rare entity is usually isolated and detected incidentally in 0.6-5.

Atypical MRI features of a biliary cystadenoma revealed by jaundice.

We report on the case of a patient admitted for epigastric pain. An abdominal ultrasound revealed a voluminous cystic lesion of the left hepatic lobe. In magnetic resonance imaging, the mass had a liquid-liquid level that was spontaneously hyperintense on T(1)-weighted images and hypointense on T(2)-weighted images.

Emergency laparotomy for misdiagnosed biliary cystadenoma originating from caudate lobe.

Background: Biliary cystadenoma is a rare benign neoplasm, which is often misdiagnosed for a hepatic abscess or a hydatid cyst that tends to recur and is at risk for progression to malignant neoplasm.

Case Presentation: This case describes a 30-year-old woman admitted to our institution in an emergency setting. The patient was originally misdiagnosed as affected by a hepatic hydatid cyst at another hospital, and then emergently treated at our Institution for severe abdominal pain.

Obstructive jaundice due to hepatobiliary cystadenoma or cystadenocarcinoma.

Hepatobiliary cystadenomas (HBC) and cystadenocarcinomas are rare cystic lesions. Most patients with these lesions are asymptomatic, but presentation with obstructive jaundice may occur. The first patient presented with intermittent colicky pain and recurrent obstructive jaundice.

Biliary cystadenoma and other complicated cystic lesions of the liver: diagnostic and therapeutic challenges.

Introduction: Biliary cystadenomas are complicated cystic lesions of the liver. They are rare and pose considerable diagnostic and therapeutic challenges.

Methods: We present our experience managing these lesions by performing a retrospective review of all patients with a preoperative diagnosis of or histologically proven biliary cystadenoma who underwent surgery between January 1995 and January 2005 at our institution.

Hepatobiliary cystadenoma: a case report and a review of the literature.

Background: Hepatic cystic lesions are rare; however, their management and treatment is dependent on early recognition and diagnosis.

Methods: In this report, the authors discuss a 72-year-old woman who presented to their clinic for treatment of a hepatocystadenoma.

Results: The history, physical examination, and diagnostic modalities lead to surgical intervention despite an unclear diagnosis.

[Peritoneal hepatobiliary cystadenoma--case report].

Hepatobiliary cystadenoma with mesenchymal stroma are infrequent form of cystic neoplasm that may be found in females only. It is difficult to reach correct diagnosis prior to surgery. We are presenting a case of 32 years-old female referred to our institution for revealing a cause of discomfort and pain in right subcostal region whereas peritoneal hepatobiliary cystadenoma has been determined.

Large mucinous biliary cystadenoma with "ovarian-like" stroma: a case report.

Hepatobiliary cystadenomas are rare tumors that are difficult to diagnose preoperatively. They can reach large sizes that make them real intraoperative "surprises". A 63-year-old woman, presented with a symptomatic huge abdominal cystic mass, underwent complete resection of the mass with safety margins.

[Significances of serum level and immunohistochemical stain of CA19-9 in simple hepatic cysts and intrahepatic biliary cystic neoplasms].

Background/aims: In spite of various diagnostic modalities, biliary cystic neoplasms (biliary cystadenoma and cystadenocarcinoma) remain to be difficult to diagnose preoperatively. Recently, there are some reports that elevated CA19-9 level in serum and/or cystic fluid could be a useful finding in the differential diagnosis of biliary cystic neoplasm. This study aimed to evaluate the expression of CA19-9 and to elucidate its significances in intrahepatic biliary cystic neoplasms and simple hepatic cysts.

[Biliary cystic neoplasm: biliary cystadenoma and biliary cystadenocarcinoma].

Biliary cystic tumors, such as cystadenoma and cystadenocarcinoma, are rare cystic tumors of liver accounting for fewer than 5% of all intrahepatic cysts of biliary origin. Most biliary cystic tumors arise from intrahepatic bile duct and 10-20% arise from extrahepatic bile duct like common hepatic duct, common bile duct, and gallbladder. The first case report of biliary cystic neoplasm in Korea dated back to 1975 by Bae et al, and over 40 cases of cystadenoma and 35 cases of cystadenocarcinoma were reported since then.

[Obstructive jaundice caused by portal varicosis].

In a 66-year-old woman with pruritus, jaundice, dark-brown urine and light-colored faeces obstructive jaundice was diagnosed. Despite extensive investigations, it was not possible to clearly distinguish if varicosis or cholangiocarcinoma was the cause of the obstruction. During laparotomy the right lobe of the liver was seen to be greatly underdeveloped.
