A Case Report on Lyphosarcoma in a Calf

Abstract

A 7-month-old female calf showed symptoms of leukosis, weight loss, lymphocytosis, exophthalmos, and remarkable swelling of general lymph nodes. Infiltration and accumulation of atypical lymphoid cells were observed in the lymph nodes, heart, abomasum, small intestine, uterus and brain, but not in Glisson's sheath of the liver, bone marrow, or thymus. These lesins were similar to those in leukosis of adult type.
On the farm where the calf was kept, the rate of cows positive for BLV-antibody test was 28-52%. The calf had also BLV-antibody, but no BLV could be isolated from her. In brief, these lesions were similar to those of the adult cow, although they were presented by the calf 7 months of age.
