Posttransplantation lymphoproliferative disorder of the paranasal sinuses in a child

Summary 

Posttransplantation lymphoproliferative disorder (PTLD) represents an often fatal complication of chronic immunosuppression following solid organ or bone marrow transplantation. PTLD in the head and neck is uncommon and generally involves lymphoproliferation in Waldeyer's ring, cervical lymphadenopathy, or both. This unusual case of PTLD involving the paranasal sinuses in a child illustrates the difficulty in distinguishing PTLD from invasive fungal sinusitis. Promptly establishing the correct diagnosis via biopsy is critical to the successful management of such a patient.
