OTOKIDA, K., YOSHIDA, H., MIZUNUMA, Y., YAMADA, M. and HIRAMORI, K. Multiple Myeloma Associated with Amyloidosis and t(1;20)(q21;q11) Translocation. Tohoku J. Exp. Med., 1990, 162 (4), 363-365 - 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 λ-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.
