Concurrent Presentation of Light Chain Amyloidosis and Renal Cell Carcinoma in an Elderly Male : A Case Report and Review of the Literature

Abstract

Amyloidosis is often known as “the great imitator,” as the clinical diagnosis of AL amyloidosis is quite challenging and often delayed, given multi-organ involvement. We present a unique case of an elderly male who presented with an eight-month history of progressive lower extremity edema and dyspnea and was admitted for syncope, anasarca, and severe dyspnea. He was diagnosed with renal failure, nephrotic syndrome, a large renal mass, and severe non-ischemic cardiomyopathy. A renal resection was performed, and renal cell carcinoma (RCC) and light chain (AL) amyloidosis were diagnosed.
