Renal vein thrombosis in renal cell carcinoma. Proteinuria as diagnostic sign

Paraneoplastic oesophageal dysmotility-renal cell carcinoma presenting as dysphagia: a case report

INTRODUCTION

Dysphagia and weight loss are alarming symptoms that warrant urgent assessment.

CASE PRESENTATION

We present a case report of dysphagia secondary to oesophageal dysmotility attributed to a paraneoplastic manifestation of an occult renal cell carcinoma.

CONCLUSION

We believe this patient's dysphagia was a paraneoplastic manifestation of the renal cell tumour, an association that has never been previously reported. This case demonstrates the need to look for alternative causes for dysphagia if initial investigation and treatment are unhelpful. Importantly, this must include the consideration of a paraneoplastic process secondary to an occult neoplasm.

Acute renal vein thrombosis in adults

We had the chance to follow up 7 adult patients with acute R.V.T. for 3 years. Four patients had positive histories of either diagnosed or undiagnosed renal trouble. Dehydration was the most prominent predisposing factor seen in 3 cases of pilgrims due to low fluid intake and hard physical effort in severe hot weather (42-44 degrees C). Massive haematuria and severe lumbar pain were the most characteristic clinical symptoms. With the aid of ultrasonography, we were able to detect perirenal collections in 4 cases. Careful clinical examination, retrograde pyelography and ultrasound examination were found to be non-invasive diagnostic modalities.
