Small-Sized Clone of T Cells in Multiple Myeloma Patient after Auto-SCT : T-LGL Leukemia Type or Clonal T-Cell Aberration?

الملخص EN

Second cancers and particularly postransplant lymphoproliferative disorders (PTLDs) are extremely rare in patients undergoing autologous peripheral blood stem cell transplantation (auto-SCT).

We report the case of clonally rearranged T-cell expansion which occurred after auto-SCT for Multiple Myeloma (MM).

Does asymptomatic clonal T-cell large granular lymphocytic proliferation, in our experience, represent either a secondary cancer after auto-SCT or clonal T cell aberration or derive from expansion of coexisting undetected small-sized clone of T cells?
