Hepatobiliary cystadenomas.

Introduction: Hepatobiliary cystadenomas are rare cystic tumours that can arise from any portion of the biliary tract but most commonly develop intrahepatically. They typically cause non-specific symptoms and are often detected incidentally. Cystadenomas can be mistaken for simple hepatic cysts on radiological imaging, which leads to inadequate treatment.

Current management of noninfectious hepatic cystic lesions: A review of the literature.

Nonparasitic hepatic cysts consist of a heterogeneous group of disorders, which differ in etiology, prevalence, and manifestations. With improving diagnostic techniques, hepatic cysts are becoming more common. Recent advancements in minimally invasive technology created a new Era in the management of hepatic cystic disease.

Hepatic pseudocystic metastasis of well-differentiated ileal neuroendocrine tumor: a case report with review of the literature.

Unlabelled: Imaging appearance of cyst-like changes is most frequently described in primary neuroendocrine lesions, especially pancreatic NETs.The imaging finding of a pseudocystic lesion of the liver puts in differential diagnosis many pathologies such as infectious diseases, simple biliary cysts up to biliary cystadenomas and eventually to primary or metastatic malignancies.Primary or metastatic hepatic malignancies with pseudocystic aspects are rare, and a pseudocystic aspect is reported only after neo-adjuvant treatment.

Spectrum of multilocular cystic hepatic lesions: CT and MR imaging findings with pathologic correlation.

A multilocular cystic hepatic lesion detected at computed tomography (CT) and magnetic resonance (MR) imaging is a common but nonspecific radiologic finding that can cause potential challenges for differential diagnosis. This imaging pattern may be observed in a wide spectrum of common and uncommon neoplastic or nonneoplastic entities. Neoplastic lesions include cystadenoma, cystadenocarcinoma, hepatocellular carcinoma (HCC), metastases, mesenchymal hamartoma, and inflammatory myofibroblastic tumor.

Management of giant hepatic cysts in the laparoscopic era.

Purpose: We sought to evaluate the feasibility and outcomes of laparoscopic resection of giant hepatic cysts and surgical success, focusing on cyst recurrence.

Methods: From February 2004 to August 2011, 37 consecutive patients with symptomatic hepatic cysts were evaluated and treated at Dong-A University Hospital. Indications were simple cysts (n = 20), multiple cysts (n = 6), polycystic disease (n = 2), and cystadenoma (n = 9).

Asymptomatic hepatobiliary cystadenoma of the hepatic caudate lobe: a case report.

Human hepatobiliary cystadenoma is a rare benign cystic tumor of the liver, and is extremely rare in the caudate lobe. We herein present a case of a 70-year-old male with a hepatobiliary cystadenoma originating from the caudate lobe.

Evaluation of hepatic cystic lesions.

Hepatic cysts are increasingly found as a mere coincidence on abdominal imaging techniques, such as ultrasonography (USG), computed tomography (CT) and magnetic resonance imaging (MRI). These cysts often present a diagnostic challenge. Therefore, we performed a review of the recent literature and developed an evidence-based diagnostic algorithm to guide clinicians in characterising these lesions.

Clinicopathological subclassification of biliary cystic tumors: Report of 4 cases with a review of the literature.

Biliary cystic tumors are rare hepatic neoplasms, and knowledge regarding the origin and pathology of these tumors remains vague. They should be analyzed in more detail. In our institution, 4 biliary cystic tumor surgeries were performed between December 1999 and March 2010.

[Pancreatectomy for the pancreatic tumors].

23 pancreatectomies were made on the reason of various tumors of the pancreas during the period of 2009-2012yy. 15 patients had duct adenocarcinoma, 4 - neuroendocrine neoplasia, 2 - intraductal papillary-mucinous tumor, 1 had metastase of renal-cell carcinoma and 1 was diagnosed with serous cystadenoma. Pancreatectomy was indicated in case of invasion of the whole pancreas or in case of multiple tumor focuses.

Hepatobiliary cystadenoma: a rare pediatric tumor.

Hepatobiliary cystadenoma is a rare hepatic neoplasm that has been reported only 10 times in the pediatric population. Although considered a benign cystic tumor of the liver, hepatobiliary cystadenoma has a high risk of recurrence with incomplete excision and a potential risk for malignant degeneration. Complete tumor excision with negative margins is the mainstay in treatment.

Filling Defect on ERCP: Biliary Cystadenoma, a Rare Tumor.

Biliary cystadenomas are rare tumors of the bile ducts most commonly presenting as large right liver lobe lesions. These are usually slow-growing and mostly benign. They commonly present with abdominal pain.

Hepatic endometriosis diagnosed by liquid-based cytology: a case report.

A 44-year-old woman presented to Emergency Department with sudden onset of severe upper abdominal pain. T2-weighted MRI image showed a large cystic mass with a thickened wall measuring 9.5 × 9.

Surgical management of cystic lesions in the liver.

Background: Liver cysts are common, occurring in up to 5% of the population. For many types of cysts, a variety of different treatment options exist and the preferred management is unclear.

Methods: A PubMed and Medline literature review was undertaken and articles pertaining to the diagnosis and management of cystic lesions within the liver were retrieved.

Giant mucinous cystic neoplasms of pancreas and liver with unusual adipose tissue component: a case report.

Simultaneous occurrence of pancreatic and hepatic mucinous cystic neoplasms is very rarely reported in the literature. We present a case with extensive fatty component of the pancreatic tumour arising from the head of the pancreas and attaining a huge size before being treated by Whipple's pancreatoduodenectomy and subsequently by a right hepatectomy for the hepatic tumour.

Hepatic endometrioma: a case report and review of the literature: report of a case.

Hepatic endometriosis has an extremely rare occurrence characterized by the presence of ectopic endometrium in the liver. A diagnosis of hepatic endometriosis is established after surgery. A 51-year-old multiparous female was referred to our unit for investigation of a liver tumor.

Segment I intrahepatic biliary cystadenocarcinoma impinging on the hepatic vein.

Background: Biliary cystadenoma is a rare cystic tumor; prognosis is dependent on the completeness of the surgical resection.

Case Report: The case of a 65-year-old woman with a multilocular cystic hepatic tumor is reported. Radiological and laboratory findings suggested the diagnosis of cystadenoma with localized malignant degeneration.

Enhancer of zeste homologue 2 (EZH2) is a reliable immunohistochemical marker to differentiate malignant and benign hepatic tumors.

Background: The immunohistochemical demonstration of Enhancer of zeste homologue 2 (EZH2) proved to be a useful marker in several tumor types. It has been described to distinguish reliably hepatocellular carcinomas from liver adenomas and other benign hepatocellular lesions. However, no other types of malignant liver tumors were studied so far.

Biliary cystadenomas: a case for complete resection.

Introduction and Objective. Biliary cystadenoma is a rare benign neoplasm of the liver with less than 200 cases being reported allover the world. We report a series of 13 cases highlighting the radiological findings and problems related to its management.

Intra and extra-hepatic cystadenoma of the biliary duct. Review of literature and radiological and pathological characteristics of a very rare case.

Painless obstructive jaundice is often associated with a malignant disease of the common bile duct or head of the pancreas. The authors present a unique case of a 62-year-old woman affected by an intrahepatic cystadenoma that extended into the common biliary duct. To our knowledge no previous case reports have been published on similar cases.

Surgical management of cystic lesions in the liver.

Background: Liver cysts are common, occurring in up to 5% of the population. For many types of cysts, a variety of different treatment options exist and the preferred management is unclear.

Methods: A Pubmed and Medline literature review using key words non-parasitic hepatic cysts, polycystic liver disease, echinococcus, hydatid cysts parasitic cysts, Caroli's disease, cystadenoma; liver abscess, surgery, aspiration and treatment was undertaken and papers pertaining to the diagnosis and management of cystic lesions within the liver were retrieved.

Mucinous cystadenoma of the liver with ovarian-like stroma: the need for complete resection.

Cystadenoma of the liver is a rare neoplasm. Although many cystadenomas are asymptomatic, symptoms can include abdominal pain, postprandial epigastric discomfort, and nausea. Dramatic changes in hepatic imaging techniques have been helpful for diagnosing cystic lesions of the liver, such as simple cyst, hydatid cyst, cystadenoma, cystadenocarcinoma, and metastatic neuroendocrine tumors.

Clinical outcome and long term results after surgical treatment of biliary cystadenoma and cystadenocarcinoma.

Backgrounds/aims: Biliary cystadenoma (BCA) and cystadenocarcinoma (BCCA) are rare cystic hepatic neoplasms. Prior reports concerning the proper surgical treatment and long-term survival are scarce. We report our experience and survival outcome of 30 patients over the last 25 years.

Intraductal papillary neoplasm arising from peribiliary glands connecting with the inferior branch of the bile duct of the anterior segment of the liver.

Intraductal papillary neoplasms of the bile duct are generally thought to arise from neoplastic papillary proliferation of epithelial cells lining the bile duct. We herein report a case with findings that strongly suggested that the biliary cystic tumor might have derived from a peribiliary gland. A 69-year-old female was found to have a cystic lesion with intracystic protrusions at the anterior segment of the right hepatic lobe and underwent hepatic anterior segment resection.
