Painless jaundice and unexplained weight loss is an exceedingly rare presentation for renal cell carcinoma (RCC). Such a presentation is more typical of a hepatocellular pathology. Stauffer syndrome is a paraneoplastic syndrome seen in RCC and is characterized by deranged hepatic enzymes and in association with fever, fatigue and weight loss. These symptoms typically resolve following nephrectomy. The predominant picture of this syndrome is that of an anicteric patient. Here we report the case of a 48 year old man who presented with a 3 week history of painless jaundice, malaise, anorexia and unintentional weight loss of 10 kilograms. Imaging revealed a solid right renal mass measuring 11 cm × 11 cm × 14 cm. There were also findings consistent with the presence of an inferior vena cava thrombosis and multiple pulmonary lesions. Biopsy confirmed the pulmonary lesions as metastatic clear cell renal carcinoma. Following multi-disciplinary discussion, cytoreductive nephrectomy was recommended to the patient, however multiple paraneoplastic syndromes subsequently developed and the patient experienced hypertension, severe coagulopathy and hypercalcaemia. Subsequently, the patient opted for supportive and palliative care. The patient died 2 weeks after initial presentation. Paraneoplastic syndromes associated with RCC are often underdiagnosed due to their variety and often non-specific nature. Paraneoplastic syndromes may lead to patient presentation, where they often suggest advanced or metastatic disease, and those caring for such patients should remain vigilant as further syndromes may complicate patient care.
