Abstract

Amyloidosis is a rare complication of non-Hodgkin's lymphoma (NHL). AL amyloid deposits are usually localized in areas adjacent to the lymphoma, despite the presence of circulating light chains. However, AA-type amyloidosis is extremely unfrequent as a residual mass in patients with NHL. We report a case with diffuse large B-cell non-Hodgkin's lymphoma in which a residual tumoral mass corresponding to AA-type amyloidosis was found.
