| Summary: | A 65-year-old man with nonsevere aplastic anemia received rabbit anti-thymocyte globulin and cyclosporine and partially responded. Six months after the initiation of treatment, he was diagnosed with stage IV angioimmunoblastic T-cell lymphoma and received chemotherapy. PET/CT scan analysis indicated a complete response. However, he showed sustained myelosuppression and was diagnosed with relapse of aplastic anemia. He did not respond to cyclosporine, eltrombopag or methenolone. Fifteen months after eltrombopag administration, he developed MDS with t(3;21)(q26.2;q22). Patients should be monitored carefully for the emergence of not only -7/del(7q) but also 3q26 abnormalities, including t(3;21)(q26.2;q22), during and after eltrombopag treatment.
