Concurrent lymphosarcoma and salmonellosis in a 12-year-old female neutered domestic shorthair cat in Grenada is described. Clinically, the cat was emaciated, and had a history of vomiting and diarrhea of two months duration. Clinical examination revealed a large palpable mass in the craniodorsal abdomen and fluid in the thoracic cavity. Gross lesions consisted of moderate pyothorax and pyoabdomen with variably-sized, single to multiple, soft, white masses in the mesentery adjacent to the pancreas, on the serosal surface of the stomach, and on the quadrate lobe of the liver. Histopathological findings associated with these masses were compatible with lymphosarcoma. Sheets of neoplastic round cells, some with intracytoplasmic eosinophilic granules, were found in the masses associated with the omentum, stomach, and liver. Salmonella enteritidis was isolated in pure culture from the thoracic fluid, collected during clinical examination, and mesenteric mass, collected during necropsy, and both isolates showed similar antimicrobial susceptibility patterns.
