Enzootic bovine leucosis is an infectious disease of cattle caused by the bovine leukemia virus that results in lymphoma within target tissues. Cattle might demonstrate four clinicopathological age-related manifestations of the disease: juvenile, adult, thymic, and cutaneous form. This article describes the unusual manifestation of this disease in a 4-yr-old cow. Regional lymph nodes were enlarged during clinical examination. Peripheral and internal lymph nodes, as well as the vagina, uterus, spleen, liver, heart, thoracic vertebrae, eye and the thoracic and abdominal cavities demonstrated lymphoma at necropsy. Bovine enzootic leucosis was confirmed by histopathology and agar gel immunodifusion.
