    A five-year-old male rabbit was presented with the request of necropsy. Post mortem examination revealed a mass in the cranial mediastinum. Histopathologically, it was seen that the mass consisted of a limited mesenchymal tissue with medium-sized mature lymphocytes and a large proportion (approximately 90%) of lymphoblast-like round cell infiltration. While tumour cells were stained positively for CD3, they were negative for CD79a. Pan-Cytokeratin was localized in small number of epithelial cells in the background. Histopathological and immunohistochemical evaluation showed that the case was compatible with thymic lymphoma and it was the first case reported in rabbits in Turkey.

    The carcasses of three 1-year-old, Leghorn chickens were presented for necropsy; one of the chickens was told to have shown neurological signs before death. At necropsy, meningeal and cerebral hyperemia were observed in the carcass that had neurological symptoms, and diarrhea was evident in the other two chickens. Histopathological examination revealed nonsuppurative meningoencephalitis, myositis in skeletal and cardiac muscles, and focal nonsuppurative hepatitis, and nephritis. Bradyzoites and tachyzoites were present in the meninges and brain. The present case is the first report of Toxoplasma gondii infection in a chicken in Turkey.
