The bile duct cystadenoma is a very rare, premalignant cystic lesion that only about less than 100 cases were reported in the literatures. The lesions occur most often in middle-aged woman characterized by epigastric discomfort, right upper
quadrant
pain and palpable mass.
@EN The etiology of the cystadenoma is still unknown.
It is believed that cystadenocarcinomas are derived from benign cystadenomas, because most of the malignant tumors contain a considerable amount of benign epithelium. And complete excision is the ideal treatment for bile duct cystadenoma because
it
is a
true neoplasm.
A 64 years old female patients was admitted to this hospital with the complaints of intermittent right upper quadrant pain and lower abdominal pain with palpable mass.
Exploratory laparotomy was performed which disclosed a hard, smooth and round cyst mass, about 7 cm in diameter in the left hepatic lobe. The cut surface of the tumor showed multiloculated appearance. The cyst was seperated with a septum, and had
well
developed wall, containing serosanguineous fluid and multiple pigment stones.
Histopathological examination confirmed confirmed the cystadenoma of the bile ducts.
