Abstract
A 52-year-old woman presented with a 1-year complaint of unexplained/undesired weight loss of 13 lbs. Additional symptoms derived on review of systems included chills, night sweats, fatigue, and pain at the base of her tongue. Standard laboratory values demonstrated slight anemia and increase in serum creatinine. Subsequent biopsy of the base of tongue spot demonstrated amyloid deposition. Urine protein electrophoresis demonstrated elevated free lambda light chain, and bone-marrow biopsy demonstrated elevated levels of clonal plasma cells, consistent with diagnosis of multiple myeloma with associated amyloidosis.
The patient then underwent high-dose chemotherapy followed by allogenic stem cell transplantation with stabilization of the disease process. On follow-up examinations after initial therapy, the patient complained of new areas of nodularity involving the tongue, eyelids, and lower abdomen. The left lower abdomen was biopsied and pathologic results demonstrated myeloma/plasmacytoma. Additional involvement of the heart and GI tract was noted during the patient’s workup.
