Abstract
OBJECTIVE: To report a rare case of paraneoplastic jaundice as a manifestation of prostate cancer. CLINICAL PRESENTATION AND INTERVENTION: We report on a case of paraneoplastic syndrome in a 72-year-old man with prostate cancer that manifested with idiopathic jaundice. Although steroids can be used as treatment in patients with prostate cancer, they could exacerbate paraneoplastic jaundice. The jaundice that flared up after treatment with 40 mg prednisone was improved with antiandrogen treatment. CONCLUSION: Physicians should be aware of the possibility of paraneoplastic jaundice in patients with prostate cancer. Appropriate antiandrogen therapy should be considered for paraneoplastic jaundice in these patients.
