title: Peripheral T-Cell Lymphoma: A Posttransplant Lymphoproliferative Disorder Presenting as a Jejunal Mass in a Renal Transplant Recipient.
abstract: Posttransplant lymphoproliferative disorders are a spectrum of lymphoproliferative disorders seen in recipients of solid-organ, bone marrow, and stem cell allografts. They include polyclonal early lesions mimicking infectious mononucleosis and monoclonal proliferations of B and T cells, indistinguishable from lymphomas occurring in immunocompetent individuals. Although most posttransplant lymphoproliferative disorders are B-cell neoplasms, T-cell posttransplant lymphoproliferative disorders are very rare. Among solid-organ transplants, renal allografts have low risk for development of posttransplant lymphoproliferative disorders. We describe the case of an adult male who developed a T-cell posttransplant lympho?roliferative disorder involving the small intestine after renal transplant, which was diagnosed as peripheral T-cell lymphoma, not otherwise specified.
