What is biliary cystadenocarcinoma?
Biliary cystadenoma, a rare tumor of the liver, originates from the biliary epithelium of the liver. It grows very slowly; however, there are also tumors that can reach 12 cm in diameter. It is more common in middle-aged women than in men. Although it is usually benign, it can turn into malignant tumors over time.
What are the symptoms of biliary cystadenocarcinoma?
Because these tumors grow very slowly, they do not show any physical examination findings. It is usually noticed by chance; however, people diagnosed with a tumor typically experience complaints such as abdominal pain, bloating, nausea and vomiting.
What methods are used to diagnose biliary cystadenocarcinoma?
Although liver test results are normal in these patients, elevations in alkaline phosphatase, bilirubin and, less commonly, aminotransferase levels may be observed.
Imaging methods such as ultrasound, computed tomography (CT) and magnetic resonance (MRI) are used to distinguish biliary cystadenocarcinoma tumors from other tumors and cystic structures of the liver.
How are biliary cystadenocarcinoma tumors treated?
Surgical treatment methods are used for these tumors. The entire tumor is removed surgically. Biliary cystadenocarcinomas require close follow-up due to the possibility of recurrence.
