Eosinophilic gastroenteritis syndrome in a dog

Summary

We performed a clinical and pathological study of a 5 year old female mongrel dog (Drahthaar) with eosinophilic gastroenteritis. The animal was presented with vomiting and was reported to have had bloody diarrhoea for 4 months. The lesions were in atypical locations: in the fun‐dus of the stomach, the ileocaecal valve and the rectum, near the anal sphincter. The lesions in the stomach wall were particularly severe and included severe fibroplasia, especially in the muscle layer and submucosa. Fibroplasia was less visible in the other locations. The presence of eosinophilic granulomatous masses led us to suspect a possible parasitic infection, although some authors note that this pathological condition may have an allergic aetiology.
