Abstract:
Lymphosarcoma is considered to be the most common neoplasm of the pig even more common than embryonal nephroma. In the present study, five cases of 4-5months old pigs were affected with lymphosarcoma with history of gradual decrease in body weight and anaemia. Grossly mesenteric lymphnodes were greately enlarged and hemorrhagic. Endocardial hemorrhages, hemorrhagic patch on gastric mucosa, hemorrhagic enteritis and severe congestion of the liver, mesenteric blood vessels were noticed. Cytology revealed numerous enlarged lymphocytes with basophilic cytoplasm and increased number of mitotic figures in lymphnodes. Pasteurela multocida organisms were also observed in the impression smears of heart and liver. Histopathological examination revealed infiltration of numerous lymphoblasts and distortion of normal architecture in lymphnodes. Because of immunosuppressive effect of lymphosarcoma, secondary bacterial infections mainly pasteurellosis were noticed which might be the cause of sudden death.
