Abstract：BACKGROUND:Acute myeloid leukemia after liver transplantation is a rare complication with high mortality. OBJECTIVE:To study the clinical features of acute myeloid leukemia after liver transplantation. METHODS:One case of acute promyelocytic leukemia after liver transplantation was reported, and literatures were reviewed. RESULTS AND CONCLUSION:Case presentation was post-odontectomy bleeding with associative abnormal coagulation test at 85 months after liver transplantation. Routine blood test, bone marrow test and chromosome analysis and examination diagnosed as acute promyelocytic leukemia and promyelocytic leukemia/RARαpositive chimeric gene, and clearly diagnosed as acute promyelocytic leukemia combined with disseminated intravascular coagulation. The patient received fresh frozen plasma transfusion to correct the abnormal coagulation, and then received induction chemotherapy with retinoic acid, arsenic trioxide and daunorubicin to obtain bone marrow complete remission. The patient was treated with daunorubicin combined with cytarabine and mitoxantrone combined with cytarabine regimens after remission induction to consolidate the chemotherapy for two courses of treatment, and then subsequently subjected to arsenous acid chemotherapy, and the bone marrow was sustained for remission. During chemotherapy, the dose and type of immunosuppressive agents were adjusted, and the patient had stable liver function without serious infection or complications. The results indicate that acute myeloid leukemia is common and often occurs after liver transplantation. When the patient displays hematological abnormality, acute promyelocytic leukemia should be considered. Early diagnosis and treatment can reduce the mortality.
