Prostate Cancer Presenting with Pruritus and Cholestasis.

Jaundice is a rare symptom of the paraneoplastic syndrome associated with prostate cancer. We report a case of metastatic prostate cancer that presented as jaundice. There was an absence of biliary obstruction and hepatic metastasis; therefore, the paraneoplastic syndrome was suggested as the etiology of cholestasis. Jaundice improved with the treatment of prostate cancer. In the literature, interleukin-6 has been suggested to be associated with paraneoplastic syndrome.
