2.Histopathology of a benign bile duct lesion in the liver: Morphologic mimicker or precursor of intrahepatic cholangiocarcinoma.
Clinical and Molecular Hepatology 2016;22(3):400-405
A bile duct lesion originating from intrahepatic bile ducts is generally regarded as an incidental pathologic finding in liver specimens. However, a recent study on the molecular classification of intrahepatic cholangiocarcinoma has focused on the heterogeneity of this carcinoma and has suggested that the cells of different origins present in the biliary tree may have a major role in the mechanism of oncogenesis. In this review, benign intrahepatic bile duct lesions—regarded in the past as reactive changes or remnant developmental anomalies and now noted to have potential for developing precursor lesions of intrahepatic cholangiocarcinoma—are discussed by focusing on the histopathologic features and its implications in clinical practice.

Hepatobiliary cystadenomas are rare cystic neoplasms that often occur in middle aged women. The exact etiology of these tumors is unknown. Diagnosis is often delayed in these cases. However, misdiagnosis and inappropriate treatment may result in unfavorable outcome. We report a case of hepatobiliary cystadenoma with pleural effusion. We also review the literature and discuss the current diagnostic and treatment modalities.

GIST is a rare neoplasm, the majority of GISTs are located in the stomach and small intestine. Most GISTs are diagnosed histopathologically after resection because of submucosal location. A 37-year-old female patient presented with a 2-weeks history of generalized weakness, nausea accompanied by intermittent passage of black, tarry stools. Esophagogastroduodenoscopy and ERCP showed a large round mass measuring 5 cm in diameter in the ampulla of Vater with ulcer crack. Endoscopic multiple biopsies from the mass including ulcer base were taken. Light microscopic findings showed spindle-shaped and epitheloid tumor cells having high cellularity and frequent mitotic figures. On immunohistochemical stainings, the tumor cells were positive for CD34 and smooth muscle actin. Based on these preoperative findings, a diagnosis of malignant GIST of the ampulla of Vater was made probably. After operation, immunohistochemical studies revealed positive reaction for c-kit and vimentin, as well as focally reactive for CD34 and smooth muscle actin. We report a case of GIST in the ampulla of Vater presenting with melena that was diagnosed preoperatively and postoperatively.

Leiomyomas, originating in the bile duct, are very rare, and only few cases have been reported in the literature. We experienced a case of leiomyoma of the distal common bile duct, mimicking bile duct cancer. A 39-year-old woman presented with intermittent jaundice and general weakness for three months. Clinical profiles showed obstructive jaundice, and the abdominal computed tomography and cholangiography revealed diffuse bile duct dilatation with distal common bile duct stricture. A pylorus-preserving pancreaticoduodenectomy was performed and the pathologic specimen disclosed leiomyoma of the common bile duct accompanying severe fibrosis. This is the first case of leiomyoma in the bile duct reported in Korea.

Combined hepatocellular carcinoma and cholangiocarcinoma is found at a frequency of 1.0~6.3% in resected primary hepatic tumors. However, the case of double cancers of hepatocellular carcinoma and cholangiocarcinoma that are discovered synchronously in different lobes of a liver is very rare. We experienced a case of a 74-year-old man who was found to have hepatocellular carcinoma and cholangiocarcinoma in different lobes of the liver, which were accompanied by early gastric cancer. To our knowledge, this is the first case report of double primary hepatic cancers accompanied with early gastric cancer. The pathogenesis and previous related reports of these lesions are discussed.
