Secondary intestinal lymphangiectasia in a dog - a case report.

This paper describes in detail the clinical and pathomorphological aspects of lymphangiectasia in a dog.The dog was presented at the Clinic for Internal Diseases, Faculty of Veterinary Medicine, Zagreb, after a period of chronic diarrhoea and progressive weight loss.Results of clinical examination indicated a protein-losing enteropathy due to lymphangiectasia.Adequate therapy was conducted, but with unsatisfactory results and the dog was euthanised at the owner's request.Secondary lymphangiectasia could be due to mononuclear lymphangitis (unknown etiology) which was confirmed pathoanatomically and pathohistologically, but secondary dilatation of lacteals could be the result of inflammatory bowel disease (lymphocytic and plasmocytic infiltration).
