Immune Thrombocytopenic Purpura in a Patient Receiving Pomalidomide Treatment.

Multiple myeloma (MM) is a clonal stem disease. Immune thrombocytopenic purpura is an autoimmune disease that is chronic and resistant to immunsupresive drugs. Pomalidomide is an immunomodulatory agent used in the treatment of MM. Pomalidomide used by our patient to treat myeloma could cause bone marrow supression. On the other hand, immune system dysregulation that may be seen with immunomodulatory agents used to treat MM may trigger some immunological events. MM and immune thrombocytopenic purpura (ITP) coexcistence is very rare. Herein, we aimed to share our experience with a patient with multipl myeloma who developed ITP during pomalidomide treatment.
