Introduction
Obstructive jaundice caused by malignant tumor is commonly encountered
in daily practice in the gastrointestinal field.
Hepato-biliary-pancreatic cancers, such as liver cancer,
cholangiocarcinoma, or pancreatic cancer, are among the most common
causes of obstructive jaundice, whereas bile duct metastasis of breast
cancer is extremely rare. Herein,
we present our experience of a case of obstructive jaundice caused by
bile duct metastasis of breast cancer, in which various endoscopic
drainage procedures were performed. We believe that this is a valuable
case due to the rarity of this presentation, and have therefore reported
it with a discussion of the literature.
