Lymphosarcoma in a Boar

Abstract

A 14-month-old Yorkshire boar was examined. In the abdomen, two big tumour masses were found in the intestines. In addition, pale nodules occurred in the liver, kidneys, in and upon the spleen, in the wall of the heart and in the testicles. By immunohistochemistry tumour cells were positive for CD3, but negative for B-lymphocyte antigen and CD79. From these findings it was concluded that the boar was suffering from multicentric lymphosarcoma probably of T-cell origin.

Mucinous Adenocarcinoma and T-Cell Lymphoma in the Small Intestine of 2 Vietnamese Potbellied Pigs (Sus scrofa)

“…15 A single case of multicentric lymphoma of T-cell origin with involvement of the small intestine has been described. 18 Evidence of hereditary transmission of multicentric lymphoma in domestic pigs via an autosomal recessive gene has been documented, although the only changes noted in the small intestine of those cases were increased prominence of ileal Peyer's patches. 5 Vietnamese potbellied pigs, first brought to the United States from Canada in 1986, are widely kept as pets and have an average life span of 12-18 years, with anecdotal evidence of pigs living as long as 21 years.…”

Diffuse Multicentric Large B-cell Lymphoma Invading the Central Nervous System in a European Wild Boar (Sus scrofa)

“…There is little information on lymphoma of B-or T-cell origin in porcine species, and immunophenotypic characterization of lymphoma in swine is seldom reported in the veterinary literature (Tanimoto and Ohtsuki, 1998;Vo et al, 2004;Yang et al, 2007). Moreover, no case of lymphoma in wild boar has been described.…”
