Amyloidosis results from the pathologic deposition of beta pleated sheet fibrils within various organs including the kidney. Most often, the deposition is composed of the well-known monoclonal immunoglobulin light chains (AL) or serum amyloid A protein (AA). Recently, a new type of amyloidogenic protein was discovered, leukocyte chemotactic factor 2 (LECT2). This type of amyloid tends to have an affinity to kidney and liver and is recognized as a distinct clinico-pathologic type of amyloidosis, presenting with varying degrees of impaired kidney function and proteinuria. Herein, a case of this uncommon novel amyloidosis is presented with a brief review of the literature.
