Posttransplant Lymphoproliferative Disorders in Neuronal Xenotransplanted Macaques

Posttransplant lymphoproliferative disorders.

Posttransplant lymphoproliferative disorder is a heterogeneous group of clonal hyperplasia/neoplasms that can range from benign to highly malignant lesions. Mortality rates can approach 60%. This entity has been on the rise for the last 2 decades with the advent of highly potent immunosuppressive agents. Epstein-Barr virus has shown to play a primary role in more than 90% of the cases. Although...

Posttransplant Lymphoproliferative Disorders

Posttransplant lymphoproliferative disorders (PTLDs) are a group of diseases that range from benign polyclonal to malignant monoclonal lymphoid proliferations. They arise secondary to treatment with immunosuppressive drugs given to prevent transplant rejection. Three main pathologic subsets/stages of evolution are recognised: early, polymorphic, and monomorphic lesions. The pathogenesis of PTLD...

Posttransplant Lymphoproliferative Disorders

Thoracic presentations of posttransplant lymphoproliferative disorders.

BACKGROUND Posttransplant lymphoproliferative disorders (PTLDs) are rare complications following transplantation. Although organ-specific cases have been reported, primary presentation in the thoracic cavity has not been fully characterized. METHODS Eleven cases of PTLD with a primary thoracic presentation were identified among 3,085 solid-organ transplant patients and 1,662 bone marrow trans...

Primary central nervous system posttransplant lymphoproliferative disorders.

Posttransplant lymphoproliferative disorders (PTLDs) represent a spectrum ranging from Epstein-Barr virus (EBV)-driven polyclonal lymphoid proliferations to EBV+ or EBV- malignant lymphomas. Central nervous system (CNS) PTLDs have not been characterized fully. We reviewed the clinical, radiologic, and pathologic features of 12 primary CNS PTLDs to define them more precisely. Patients included 1...
