 AB    Prescapular lymph nodes from 109 cows seropositive to bovine leukaemia
       virus (BLV) were subjected to histologic, cytochemical and in dubious
       cases also to immunohistologic examination for the presence of light
       chains of bovine immunoglobulin (Ig) kappa or lambda. By their
       morphological features, the histologically detected changes were divided
       into B-zonal hyperplasia (23 cases, 21.1%), T-zonal hyperplasia (52
       cases, 47.7%), pulp proliferation (6 cases, 5.5%), hyperplasia of mixed
       type (18 cases, 16.5%), and atrophy (10 cases, 9.2%). Some changes
       resembled those reported in infections with human or feline
       immunodeficiency virus. Eosinophilic infiltration was a frequent
       feature. Immunohistochemical examination revealed only a lambda Ig chain
       in the cytoplasm of plasma cells or plasmacytoid cells and immunoblasts
       in pulp proliferation. Cytochemical examination showed a considerable
       number of cells with a diffuse positive reaction to acid phosphatase
       (AP).
