FOOD INTOLERANCE MIMICKING ALIMENTARY LYMPHOSARCOMA

A cat with chronic diarrhea was diagnosed as having duodenal lymphosar coma on two separate sets of endoscopic biopsies. Prednisolone failed to effect any clinical improvement. However, feeding the cat with a hy poallergenic diet resulted in long-term (i.e., six months) resolution of clinical signs. Most clinicians are familiar with the possibility o f mistakenly diagnosing inflammatory bowel disease when the patient ha s lymphosarcoma; however, this case had the opposite problem: lymphosa rcoma was diagnosed histologically on two separate occasions when infl ammatory bowel disease was the problem.
