Multiple myeloma associated with amyloidosis and t(1;20)(q21;q11) translocation.
A 59-year-old woman with nephrotic syndrome was diagnosed as having primary amyloidosis based on the detection of amyloid deposition (AL-protein) in the esophagus and kidneys. Bone marrow aspirate showed plasmocytic proliferation, leading to a diagnosis of multiple myeloma (IgG lambda-type). In addition, a very rare translocation t(1; 20) (q21; q11) was seen by chromosomal analysis of both the bone marrow and peripheral blood.
