Abstract:
Objective:To investigate the clinicpathological characteristics of post-transplant lymphoproliferative disorders (PTLD) in transplanted lung, and to improve its diagnosis and treatment.Methods:The clinicopathological characteristics of PTLD in three transplanted lungs were evaluated at Wuxi People′s Hospital Affiliated to Nanjing Medical University from 2014 to 2019. HE, immunohistochemical staining and in situ hybridization were performed. The relevant literature of PTLD was reviewed.Results:All three patients had chronic obstructive pulmonary disease (COPD) before lung transplantation. After receiving both lung transplants, they were all treated with anti-rejection drugs tacrolimus or mycophenolate mofetil, and combined with antiviral and/or rituximab. The time from transplantation to diagnosis of PTLD was four years, seven months, and five months, respectively. Two patients died one month and five months after initial diagnosis, and one patient was alive with no disease after one year. Histologically, all cases were monomorphic B-cell PTLD (diffuse large B-cell lymphoma, unspecified), and the tumor cells were positive for Epstein-Barr virus by in situ hybridization; one of the late-onset patients had herpes simplex virus infection.Conclusions:PTLD in the post-transplant lung tissue shows unique morphology and clinical characteristics, and is closely related to Epstein-Barr virus infection. Patients who receive lung transplantation due to COPD are more susceptible to develop PTLD, while late-onset ones occur more commonly in the hilum of lungs, and the prognosis is relatively poor.
