Various Clinical Presentation of Post-Transplant Lymphoproliferative Disorder in Head and Neck: A Case Series of 3 Patients / 대한이비인후과학회지

ABSTRACT

The outcome of solid organ and bone marrow transplantation has been dramatically improved with the development of immunosuppressive agent. However, the use of immunosuppressive agents could increase the risk of malignancies such as post-transplant lymphoproliferative disorder (PTLD). PTLD is regarded as the lymphoid malignancy of patients using immunosuppressive agents, and it could present diverse and non-specific symptoms. It involves various organs including the tonsil, adenoid, lymph node, and the brain. Because of its poor prognosis, an early suspicion of pathologic diagnosis is crucial for the treatment of PTLD. In this report, we demonstrate the case of three pediatric patients who had been treated for PTLD of various clinical presentations by early suspicion and pathologic diagnosis.
