A case of biliary cystadenocarcinoma with malignant seeding of the tract after percutaneous catheter drainage.

Biliary cystadenocarcinoma is rare tumor that originates from the hepatobiliary epithelium, and its clinical diagnosis is difficult during the preoperative course. A 65-year-old woman with biliary cystadenocarcinoma was misdiagnosed as hepatic abscess and underwent ultrasonography-guided percutaneous catheter drainage. Ten months later, the patient was re-admitted to our department with a mucin-producing cauliflower-like mass measuring 10x10x5 cm³ at the site of puncture.

Long-term outcome of patients with lamivudine after early cessation of hepatitis B immunoglobulin for prevention of recurrent hepatitis B following liver transplantation.

Background: The aim of this study is to examine the efficacy of long-term prophylaxis with lamivudine (LAM) after a course of post-operative hepatitis B immunoglobulin (HBIG) in patients who underwent liver transplantation (LT) for hepatitis B virus (HBV)-related disease.

Result: The medical records of HBV-infected patients who underwent a LT in our institution between July 2001 and May 2005 were reviewed. There were 15 liver transplant recipients who were administered HBIG for <18 months and used LAM as a maintenance prophylaxis regime enrolled in this study.
