After hematopoietic stem cell transplantation HSCT, presentation of localized plasmacytoma with extramedullary growth is very unusual. We report a case of a 56-year-old woman with Dune-Salmon stage IIIA immunoglobulin A-kappa multiple myeloma, which presented 120 days after autologous HSCT with extramedullary plasmacytoma arising from a lymph node in supraclavicular region. The patient had no pretransplant-history related with extramedullary disease. There was no increase of plasma cells in bone marrow or monoclonal protein in urine or serum. Aspiration smears of lymph node revealed a population of plasmacytoid cells at various stages of maturation. The patient was successfully treated with local radiotherapy and has remained progression-free for more than 20 months.}, issn = {0379-5284}, URL = {https://smj.org.sa/content/26/6/989}, eprint = {https://smj.org.sa/content/26/6/989.full.pdf}, journal = {Saudi Medical Journal} }
