Most common lymphoma sites in cattle with bovine lymphosarcoma virus?

• A. Lungs, heart, brain
• B. Right atrium, uterus, abomasum, & kidney
• C. Liver, Spleen, Pancreas
• D. Skin, muscle, bone

Answer: (B)

BLV-associated lymphosarcoma in cattle most commonly forms tumors in specific organs, with the heart (right atrium) being a classic site. Other frequent targets are the abomasum, uterus, and kidney. Tumors in these locations reflect where neoplastic B-lymphocytes tend to proliferate and form masses, which can lead to heart-related symptoms, digestive or abdominal issues, infertility or abortion, and impaired kidney function. While lymphosarcoma can involve other organs, this combination represents the most common pattern seen in infected cattle.
