Abstract:

BACKGROUND: Allogeneic hematopoietic stem cell transplantation is the main method to cure leukemia, but the patients receiving allogeneic hematopoietic stem cell transplantation still have to face the risk of recurrence. Myeloid sarcoma is a rare extramedullary relapse mode with worse clinical outcomes, so it is necessary to understand the characteristics of myeloid sarcoma and relative treatment methods.
OBJECTIVE: To analyze the clinical characteristics and treatment methods of myeliod sarcomas in cardio-phrenic angle after allogeneic peripheral blood stem cell transplantation.
METHODS: One case was diagnosed as single myeloid sacoma in the cardio-phrenic angle after allogeneic peripheral blood stem cell transplantation. The patient underwent surgical resection of the mass, chemotherapy and radiotherapy. The clinical effect, complications and survival situation were observed.
RESULTS AND CONCLUSION: The patient suffered from bacteremia, fungal pneumonia and even life-threatening sepsis shock during two courses chemotherapies. Then, the patient received radiotherapy for mediastinum and the myeloid sacoma never relapsed. However, the patient suffered central nervous system leukemia after free of the disease for 25 months. Myeliod sarcoma after allogeneic hematopoietic stem cell transplantation is rare and its manifestation is changeful. The diagnosis mainly depends on histopathology and immunohistochemistry. Surgery, chemotherapy, radiotherapy, second transplantation and molecular targeted
drugs are the choices of treatment strategy. However, the optimal treatment strategy for individual patients remains to be determined.
