Biliary cystadenoma and cystadenocarcinoma epidemiology and demographics

Introduction

Overview

Overview

Biliary cystadenoma is a rare disease. The median age at diagnosis of biliary cystadenoma is 45 years. Females are more commonly affected with biliary cystadenoma than males.

Epidemiology and Demographics

Epidemiology and Demographics

  • Biliary cystadenomas constitute less than 5% of cystic lesions of the liver.[1] Biliary cystadenoma presents as an intrahepatic lesion in 90% of cases, while in the remaining cases it involves the extrahepatic biliary tree.[2]
Age

Age

  • The majority of patients are middle-aged women with an average age of 45 at time of diagnosis.[3]
  • The peak frequency has been reported between the fourth and the sixth decades.[2]
  • However, in a few cases, cystadenomas have been observed in the second decade of life.
Gender

Gender

  • The majority of biliary cystadenomas occur in women (80-85%), and this suggested a role for hormonal influence.[2]
