Abstract

Simultaneous development of intrahepatic bile duct and gallbladder carcinoma is extremely rare. We report herein the case of an 86-year-old man found to have double cancer of the gallbladder and intrahepatic bile duct. Computed tomography and magnetic resonance cholangiopancreatography revealed a polypoid mass in the gallbladder and dilatation of the intrahepatic bile duct with intraductal papillary tumor in the left side of the liver. The patient underwent left hepatectomy, cholecystectomy with lymphadenectomy around the hepatoduodenal ligament. Pathological examination of the gallbladder revealed undifferentiated giant cell type carcinoma invading the muscularis propria. On the other hand, the liver tumor was intrahepatic intraductal papillary mucinous carcinoma in situ. Therefore, this was an extremely rare case of synchronous carcinoma of the gallbladder associated with intrahepatic cholangiocarcinoma.

Figures and Tables

Fig. 1
Contrast enhanced CT. (A) shows multiple intraductal papillary mucinous tumor in dilated left intrahepatic duct (arrow). (B) shows 2.6×3.6 cm sized polypoid mass in gallbladder with diffuse enhanced wall thickening (arrow).

Magnetic resonance cholangiopancreatography shows intraluminal polypoid mass in the gallbladder (arrow) and diffuse dilated biliary system with multifocal intraductal polypoid mass in left side intrahepatic duct (arrow head).

Fig. 3
18F-FDG PET scan shows fine lower density mass with slightly increased FDG uptake (SUVmax of 3.7) at left hepatic lobe and two prominent lower density mass with intensely increased FDG uptake (SUVmax of 8.3 at gallbladder, SUVmax of 6.2 at portocaval area), suggesting intensely FDG-avid malignant gallbladder cancer with metastasis.

Fig. 4
Gross and histologic findings of liver. (A) The cut surface of liver shows an ill-defined multilocular whitish tumor containing mucus. The adjacent hepatic ducts are dilated and have impacted black pigment stones. (B) The microscopic findings of liver shows intraductal papillary proliferation of tall columnar mucus epithelium (H&E stain, ×200; inset, H&E stain,×400).

Fig. 5
Gross and histolgic findings of gallbladder. (A) The gallbladder shows a 5.5×4×4 cm sized hemorrhagic and necrotic polypoid tumor filling the lumen. (B) The tumor cells of the gallbladder are diffusely arranged and focally syncytial large and pleomorphic tumor giant cells. The giant tumor cells demonstrate hyperchromatic nuclei with prominent nucleoli and severe mitotic activity (H&E stain, ×200; inset, H&E stain, ×400). (C) On immunohistochemistry, tumor cells are strongly positive for epithelial membrane antigen (EMA) (Immunohistochemical stain, ×200) and focally positive for CK (inset, immunohistochemical stain, ×200).
