1/2. Calcified Klatskin tumor mimicking intrahepatic stone: case report.Calcification is a relatively uncommon manifestation of malignant liver neoplasm. Calcifications in peripheral cholangiocarcinomas but not in Klatskin tumor have been reported. We present a rare case of Klatskin tumor that had dystrophic calcification mimicking a intrahepatic stone in a 65-year-old man.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/2. A new method to obtain a tissue diagnosis of proximal bile duct tumors.Klatskin tumors often pose a challenge for diagnosis and treatment. Most of these neoplasms are diagnosed clinically because of the difficulty in obtaining tissue that will provide histologic proof of the disease. When a non-operative course is sought, exhaustive attempts should be made to obtain a tissue diagnosis because of the potential for a false-positive clinical diagnosis. We describe a new way to obtain tissue for diagnosis by placing a laparoscopic choledochoscope through a percutaneous transhepatic cholangiogram track, thus allowing the tumor to be directly visualized and biopsied.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
