Orbital lesions may be the presenting sign of a systemic
disease, such as a metastatic
cancer. A metastatic
cancer of the
orbit, which has been reported to account for 2~3% of all orbital
tumor, is a
malignant neoplasm that had spread by hematogenous routes to the
orbit from a distant primary site. Although metastatic orbital
tumors are mostly from
breast,
lung,
prostate, rarely, they can be originated from
gastrointestinal tract such as
large intestine,
ileum and
pancreas. However, there has been no
report of metastatic orbital
tumor from
biliary system, until now. Herein, we
report a unique case of metastatic orbital
tumor from the
intrahepatic cholangiocarcinoma, which has been successfully controlled with systemic
chemotherapy and
radiotherapy.
