TY - JOUR T1 - Localized extramedullary relapse after autologous hematopoietic stem cell transplantation in multiple myeloma JF - Saudi Medical Journal JO - Saudi Med J SP - 989 LP - 991 VL - 26 IS - 6 AU - Muhan Erkus AU - Zahit Bolaman AU - Ibrahim Meteoglu AU - Gurhan Kadikoylu Y1 - 2005/06/01 UR - http://smj.org.sa/content/26/6/989.abstract N2 - Extramedullary plasmacytomas are rare manifestation of plasma cell malignancies. 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. ER -
