Eosinophilic granulomatous gastroenterocolitis
Eosinophilic granulomatous gastroenterocolitis is an inflammatory bowel disease of dogs characterized by diffuse intestinal thickening and eosinophilic enteritis of the stomach, jejunum, ileum, colon.
Rarely, eosinophilic masses have been reported.
Clinical signs include chronic intermittent anorexia, vomiting, diarrhea and hematochezia.
An abdominal or rectal mass is frequently noted on physical examination.
Hematological aberrations include peripheral eosinophilia, mature neutrophilia, hypoproteinemia, and hypocholesterolemia.
Histologically, the masses are composed of moderate to severe eosinophilic infiltrates, which were often transmural and accompanied by fibrosis.
Dog should not be treated surgically, as they are accompanied with a poor prognosis, but conservative treatment with prednisolone and ivermectin offers palliative responses with eventual resolution of clinical signs.
