摘要目的 探讨肾移植术后发生淋巴组织增生性疾病(PTLD)的临床及病理学特点.方法 回顾性分析3例肾移植术后PTLD患者的临床和病理学特点,并对与PTLD相关的文献进行复习.结果 3例患者肾移植后使用的基础免疫抑制剂为环孢素A或他克莫司,从接受移植到诊断PTLD的时间分别为10年、4年及2个月.病理组织学类型:2例为单形性B淋巴细胞型PTLD,1例为浆细胞增生样PTLD.确诊后的治疗包括免疫抑制剂减量及放疗和化疗.2例单形性PTLD经治疗后,患者均在1年内死亡.1例浆细胞增生样PTLD患者经治疗后,无瘤存活已42个月.结论 PTLD是发生在器官移植后具有独特形态和临床特征的淋巴组织增生异常;治疗上以免疫抑制剂减量及放疗和化疗为主;单形性PTLD预后甚差.

abstractsObjectiveTo study the clinicopathologic features of post-transplant lymphoproliferative disorders (PTLD).Methods Three cases of PTLD in renal transplant recipients were studied.The clinical data,diagnosis and differential diagnosis,and relevant literatures were also reviewed.Results All the 3 cases studied had received cyclosporine A or Tac after transplantation.The duration between organ transplantation and diagnosis of PTLD was 10 years,4 years and 2 months respectively.Two cases were suffered from monomorphic PTLD and 1 from plasmacytic hyperplasialike PTLD in morphology.Two cases of monomorphic PTLD died within one year after diagnosis.Conclusion PTLD is a lymphoproliferative disease with distinctive morphologic and clinical characteristics.The main treatments included the dosage reduction of immunosuppressive agents,radiotherapy and chemotherapy.The prognosis of monomorphic PTLD was poor.
