Epstein-Barr Virus-Positive Extranodal Marginal Zone Lymphoma of Bronchial-Associated Lymphoid Tissue in the Posttransplant Setting: An Immunodeficiency-Related (Posttransplant) Lymphoproliferative Disorder?

abstract：:Terminal deoxynucleotidyl transferase (TdT) is a marker of lymphoblastic disorders. Previously, the technique for determining TdT on smears was by indirect immunofluorescence. An immunoperoxidase procedure for detecting TdT on smears is reported. Results are in a comparable range with the indirect immunofluorescent te...
