11/271. Benign enterogenous cyst of the pancreas.A 26-year-old woman was evaluated for a mass found by computed tomography (CT). Radiographically, the mass resembled a pancreatic cystadenoma. The patient had had left upper quadrant abdominal pain for several years and low grade fevers and indigestion for 5 months. At surgery, a unilocular cystic mass was found anteriorly and caudally to the tail of the pancreas in the lesser sac. The cystic structure was connected to the pancreas by a tubular structure, which was suture ligated and divided. A review of the literature revealed this cyst to be the fifth reported case of enterogenous cyst of the pancreas. The case is unique, differing from previous reports in that ciliated respiratory epithelium, transitional epithelium, gastric mucosa, a bilayered smooth muscle wall, and a serosal surface were present in the cyst wall.- - - - - - - - - - ranking = 1keywords = cystadenoma (Clic here for more details about this article) |
12/271. Haemobilia from pancreatic cystadenoma.Hamobilia from a pancreatic source is a rare cause of gastrointestinal haemorrhage. Most of the reported cases have arisen from haemorrhage into a pancreatic pseudocyst, which is frequently fatal. This report describes a patient with gastrointestinal haemorrhage arising from a pancreatic cystadenoma.- - - - - - - - - - ranking = 5keywords = cystadenoma (Clic here for more details about this article) |
13/271. Biliary cystadenoma: rare variant of intrahepatic cystic disease.Intrahepatic nonparasitic cystic disease is rare and may be of congenital or neoplastic origin. The most frequent symptoms and signs are nonspecific and include pain, nausea, fullness, increased girth, and palpable mass. Interventional therapy is reserved for symptomatic patients, which usually corresponds to cysts >5 cm in diameter. Retrospective analysis revealed 26 cases of intrahepatic cystic disease over 15 years at our institution. We discuss the case of a patient who had bilobular biliary cystadenomatous disease, a rare, benign variant of intrahepatic nonparasitic cystic disease.- - - - - - - - - - ranking = 5keywords = cystadenoma (Clic here for more details about this article) |
14/271. Malignant transformation of biliary cystadenoma: a difficult diagnosis.The case is described of a 63-year-old female with a multilocular liver cyst diagnosed as cystadenoma after imaging and fine needle aspiration. The lesion, however, proved to be an invasive cystadenocarcinoma at surgery. cystadenoma cannot be differentiated, preoperatively, from cystadenocarcinoma and should always be considered for surgical resection.- - - - - - - - - - ranking = 5keywords = cystadenoma (Clic here for more details about this article) |

16/271. Hepatobiliary cystadenoma with mesenchymal stroma mimicking hydatid cyst. Report of a case.We report on a case of hepatobiliary cystadenoma with mesenchymal stroma in a 44-year-old Caucasian woman who presented with upper abdominal discomfort. Ultrasound (US) and computed tomography (CT) showed a cystic mass resembling hydatid cyst. Endoscopic retrograde cholangiography (ERC) demonstrated communication with the left hepatic duct. At surgery, a cystic mass with communication to the left hepatic duct was found and resected en bloc with a margin of normal liver tissue. Histological examination showed a hepatobiliary cystadenoma with mesenchymal stroma.- - - - - - - - - - ranking = 6keywords = cystadenoma (Clic here for more details about this article) |
17/271. Clinical features and imaging diagnosis of biliary cystadenocarcinoma of the liver.Biliary cystadenocarcinoma of the liver is a relatively rare disease. Herein, we reported a case of biliary cystadenocarcinoma with a review of the literature. A 71-year-old female was admitted with the chief complaint of epigastralgia. The imaging studies revealed a biliary cystadenocarcinoma in the left hepatic lobe with suspicion of direct invasion to the left and middle hepatic veins and inferior vena cava. However, there was no direct invasion of the tumor to these veins in operation findings, and an extended left hepatic resection was performed without resection of inferior vena cava. The tumor was histologically diagnosed as biliary cystadenocarcinoma of the liver. diagnosis of biliary cystadenocarcinoma is usually difficult preoperatively, however, a diagnosis was possible with the use of imaging studies. It was suggested that this tumor originated from a benign cystadenoma because of the existence of a transitional zone between normal cells and atypical cells in the cystic wall. Systematic hepatectomy was recommended as the initial treatment in consideration of the features of cystadenocarcinoma.- - - - - - - - - - ranking = 1keywords = cystadenoma (Clic here for more details about this article) |
18/271. Congenital cystadenoma of the tongue in a neonate case report with review of literature.We present a congenital cystadenoma of the tongue in a neonate, which presented at birth. Cystadenomas are uncommon tumors that form from salivary gland duct tissue and are more commonly seen in adults. This is the youngest case to be reported in the English literature. A review of literature with differential diagnosis and management is presented.- - - - - - - - - - ranking = 5keywords = cystadenoma (Clic here for more details about this article) |
19/271. Hepatobiliary cystadenoma combined with multiple liver cysts: report of a case.Hepatobiliary cystadenomas are rare benign tumors with malignant potential. They are almost always solitary lesions accompanied by multilocular cysts in the liver, and are difficult to differentiate from cystadenocarcinoma, despite the diagnostic modalities available. This report describes a case of hepatobiliary cystadenoma with multiple cysts in the left hepatic lobe, diagnosed by magnetic resonance imaging in a 48-year-old woman. Abdominal computed tomography revealed only multiple cystic lesions in the left lobe, but cholangiography via a nasogastric biliary drainage tube combined with percutaneous transhepatic cholangiography showed a stenotic region with fine irregularity in the left lateral posterior segmental bile duct and left lateral anterior segmental bile duct. Hepatobiliary cystadenocarcinoma with multiple liver cysts was suspected. We performed left hepatectomy, and microscopic examination confirmed a diagnosis of hepatic cystadenoma with multiple liver cysts. There was no nuclear atypia or mitosis in the epithelium of the locus, which was constructed of simple columnar-to-cuboidal epithelium with basal nuclei. The patient is well without recurrence more than 4 years after surgery.- - - - - - - - - - ranking = 7keywords = cystadenoma (Clic here for more details about this article) |
20/271. cystadenoma of the seminal vesicle: report of a case with ultrastructural findings.Cystadenomas of the seminal vesicles are extremely rare benign tumours. We have not been able to find more than 10 cases in the literature. A benign cystadenoma of the seminal vesicle is described in a 49-year-old man. The clinical presentation, gross appearance, microscopic characteristics, immunohistochemical and ultrastructural findings of this uncommon tumour are discussed. The purpose of this paper is to report an unusual case of cystadenoma of the seminal vesicle and review the 10 previously reported cases in the English literature.- - - - - - - - - - ranking = 2keywords = cystadenoma (Clic here for more details about this article) |
