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


  • Small intestinal T-cell lymphoma and mucinous adenocarcinoma are rarely reported in the pig, with most lymphomas being of B-cell origin and only a single report of mucinous adenocarcinoma. Two aged Vietnamese potbellied pigs had concurrent T-cell lymphoma and mucinous adenocarcinoma of the small intestine. The lymphomas formed polypoid masses that projected into the intestinal lumen, whereas the mucinous adenocarcinomas were mural masses that bulged from the serosal surface. Immunohistochemically, neoplastic cells within the lymphomas were positive for CD3 and negative for CD79a. Mucicarmine stain highlighted the abundant cytoplasmic and extracellular mucin in the adenocarcinomas.
