Cholangiocarcinoma (CCA) is a rare biliary tract epithelial malignancy. We described the clinical features of CCA patients in our institution. A 10-year retrospective study of patients with cholangiocarcinoma in University Malaya Medical Centre was conducted. Clinical data and outcomes in relation to the three anatomical groups of CCA were collected and analysed. Of the 69 patients that were included 55% were male. Mean age was 61 years. Twelve (17%) had intrahepatic, 38 (55%) perihilar and 19 (28%) distal tumour. Mean age (p=0.043), median duration of symptoms (p=0.011), jaundice (p<0.001), total bilirubin level (p=0.003), INR (p=0.005) and mean tumour size (p=0.048) were significantly related to the site of tumour. Only 12 patients had curative resection with seven R0 resections. Cholangiocarcinoma is increasingly diagnosed in our population. Despite that, the diagnosis is still often late. Age, jaundice and tumour size may predict anatomical location of CCA.

INTRODUCTION: We report a case of intrahepatic cholangiocarcinoma and portal hypertension developing in a liver with biliary microhamartomas (von Meyenburg's complex).
CASE REPORT: The patient was a 55-year-old man who had a past medical history of diffuse multiple liver abscesses. During follow-up examination, a hypovascular nodule measuring 2.1 cm in diameter was incidentally found in segment 8 of the liver. Surgical resection was performed based on a suspected diagnosis of hepatocellular carcinoma. A gastrofiberscopy examination detected characteristic findings of portal hypertensive gastropathy. During the laparotomy, multiple tiny cystic lesions were observed in a diffuse pattern across the liver surface. The liver parenchyma was slightly fibrotic and haemorrhagic. A histopathological examination revealed intrahepatic cholangiocarcinoma with vascular invasions in von Meyenburg's complex. Multiple biliary adenomas were also observed among the biliary microhamartomas adjacent to the main tumour, suggesting that the malignant transformation of the biliary adenomas might have been responsible for the development of the intrahepatic cholangiocarcinoma. The histopathologic examination also revealed sinusoidal dilation and abnormal spacing of the portal tracts and central veins as evidence of portal hypertension.

Gallstone disease is a major surgical problem in many populations; it is probably related to diet, especially excessive consumption of meat. The objective of this study was to determine the chemical composition of gallstones and their association with neoplastic changes including cholangiocarcinomas in cholecystectomised patients. The chemical composition of gallstones from 40 patients (8 males and 32 females) was analyzed. This is a prospective study performed in Baquba teaching hospital in the period from 1/10/2012 to 1/1/2013 in which we collected the gallstones for the patients who underwent cholecystectomy, whether open or laparoscopic. The stones were classified according to their chemical composition as a mixed stones (MS), and examined using a stone analysis set (chemical qualitative method) for calcium, magnesium, phosphate, uric acid and oxalate which was used reagent for qualitative determination of main individual components of stones. The results of this study showed the highest incidence of gallstones in the age group 40-49 was 13 cases followed by 11, 8 and 4 cases for age groups 30-39, 50-59, 20-29 and 60 and above, respectively. The chemical analysis showed the majority of gallstones were mixed, 38 containing calcium followed by 37 cases with uric acid, 28 with magnesium, and 25 and 22 stones with oxalate and phosphate, respectively. Microscopically, we confirmed neoplastic changes (17.5%) as cholangiocarcinomas (CCCs) (7.55%) and dysplastic cells of carcinoma in situ in 4 (10%), 31 (77.5%) cases were chronic cholecystitis and 2 (5%) cases were acute cholecystitis with empyema out of bile duct disorders patients. In conclusion, majority of cases had mixed gallstones that involved five and four of inorganic chemicals of calcium, magnesium and phosphate, the highest incidence of gallstones in age group 40-49 years old was 13 cases, and neoplastic changes were confirmed (17.5%) including CCCs, (7.5%) and dysplastic cells of carcinoma in situ (10%), while 31 (77.5%) cases were chronic cholecystitis.
