Amyloidosis and Plasma Cell Dyscrasias: A Single Institution Experience

Background: Amyloidosis is the extracellular tissue deposition of small molecular subunits of proteins as fibrils. AL Amyloidosis is a complication of underlying plasma cell dyscrasia with an associated monoclonal paraprotein. It can occur in association with multiple myeloma (MM), Waldenstrom macroglobulinemia (WM) or non-Hodgkin lymphoma. While isolated organ involvement can be seen, many patients (pts) have multiorgan involvement. Our aim was to explore the trend of amyloidosis associated with plasma cell dyscrasia, treatment and outcome at our institution. Methods: After IRB approval, we reviewed medical records of adult pts ≥ 18 years with a histological diagnosis of amyloid and had evidence of monoclonal gammopathy, between January 1st, 2010 and June 30th, 2019. We reviewed age at diagnosis, gender, work up for paraproteinemia, site of biopsy, technique used for identification of amyloid, imaging studies, treatment and outcome. Results: We found a total of 33 pts with biopsy p...
