Retroperitoneal amyloidosis as the presenting manifestation of Waldenstrom's macroglobulinaemia

BMJ Case Rep. 2013 Apr 23:2013:bcr2013009329. doi: 10.1136/bcr-2013-009329.

Abstract

Retroperitoneal amyloidosis has been described in a few case reports and is typically a secondary manifestation of inflammation or malignancy. We present the case of a 69-year-old man who presented with a large pleural effusion and an incidental retroperitoneal mass in the CT imaging. Further investigation confirmed the diagnosis of amyloid amyloidosis involving the retroperitoneum as well as a concurrent Waldenstrom's macroglobulinaemia. Chemotherapy consistent of drugs active against both the lymphoid and plasma cell components of the disease is the proposed therapy for Waldenstrom's macroglobulinaemia in those patients amenable to receive chemotherapy and can make a difference in the survival.
