[A localised histocytic sarcoma in the stomach of a dog].

A 6-year-old neutered female Bernese mountain dog is described with anorexia, weight loss and melena. Gastric neoplasia was noticed (on ultrasound) and pathological examination ofgastric biopsies showed a histiocytic tumor. Necropsy confirmed the diagnosis of a localised histiocytic sarcoma. It was remarkable that the large tumor didn't lead to vomiting.
