Cholestatic jaundice as a paraneoplastic manifestation of prostate cancer.

Paraneoplastic syndrome associated with prostate cancer is extremely rare. We report a patient who presented with cholestatic jaundice without biliary duct obstruction, hepatic involvement, or infection. After a few detailed examinations, prostate cancer was diagnosed. After treatment with bicalutamide and leuprolide, the patient's symptoms and laboratory abnormalities were reversed. Cholestatic jaundice was regarded as a paraneoplastic manifestation in this patient. The patient remains symptom-free after 14-month followup. Paraneoplastic syndrome should be considered in case of cholestatic jaundice without biliary duct obstruction, hepatic involvement, or infection.
