Hepatic Disfunction in Renal Cell Carcinoma: A Stauffer Syndrome Variant
Cholestatic jaundice is usually linked to a malignant disease when it is secondary to a mechanical obstruction of the bile duct or due to hepatic metastasis. As a paraneoplastic syndrome, cholestasis has been described in lymphoproliferative disorders, in prostate cancer and as the Stauffer syndrome with non-metastatic dysfunction in patients with renal cell carcinoma (RCC). We present the case of a 61 year old patient with a paraneoplastic manifestation with cholestatic jaundice due to RCC with kindney and lung metastases. Clinical characteristics of patients with RCC vary and sometimes manifest in a peculiar way. Cholestatic jaundice is a rare paraneoplastic syndrome associated with RCC and with the exclusion of more frequent causes, it should be taken into account in the differential diagnosis. This rare but possible association requires prompt recognition, as prognosis correlates with disease stage and influences patient’s overall survival, and an early recognition of this syndrome may improve, sometimes, patients’ outcome.
