A case report of biliary cystadenocarcinoma

Abstract

Biliary cystadenocarcinoma is a rare tumor and the 30 odd case have been reproted so far. We have recently experienced the case of biliary cystadenocarcinoma that originated in the left lobe of the liver.
The patient was a 65-year-old female who complained of anorexia and weight-loss and who was diagnosed as biliary cystadenocarcinoma by angiography, echo, C.T. and aspiration biopsy. She underwent abdominal surgery and then the metastatic lesion was found in the right lobe of the liver, so that she was inoperable. Since then, the patient's condition had gradually been deteriorating and died at last.
At necropsy, the liver weighed 1500g and some cysts were found under its capsule. On cut surface, multiple cysts were observed, ranging from thumb to fist sized. The lumens of the cysts were filled with mucinous material the cysts were white and partially solid.
Microscopically, they showed papillary cystadenocarcinoma. Some cysts were lined with malignant transformed ones. We considered that these findings revealed the malignant change of biliary cysts.
We documented this comparatively rare case with literary studies.
