S Soujanya, M Lakshman and D Madhuri
A survey was undertaken to study the occurrence of lymphoid leukosis in chicken in Rajendranagar, Hyderabad during December 2016 to July 2017. Lymphoid leukosis was diagnosed based on characteristic gross and histopathological changes in 36 poultry carcasses which were presented to postmortem examination to Department of Veterinary Pathology, College of Veterinary Science, Rajendranagar. Grossly, diffuse enlargement of liver, kidneys and spleen with multiple greyish-white foci were noticed. Whereas some birds showed multiple, variable sized soft, smooth, glistening, raised nodules on liver, kidney and heart. Cut surface of the nodule has creamy white appearance. Bursa was enlarged and showed nodular appearance. Ovaries were enlarged with soft whitish nodular masses having cauliflower like appearance. Proventriculus was enlarged and the mucosa was thickened. Microscopically, diffuse proliferation and infiltration with uniform neoplastic lymphoblast cells were noticed in various visceral organs.
