Plain-English summary

A 4-year-old stallion was brought in because he had lost his appetite and was losing weight over the past two months. He also developed diarrhea and showed signs of swelling in his belly, along with enlarged lymph nodes. Tests revealed he was anemic and had low protein levels, and ultimately, the horse was euthanized. A large mass made of granulation tissue was found in his stomach during the examination after death, but the cause of this mass couldn't be identified.

Abstract

A 4-year-old stallion was examined because of a 2-month history of inappetance and weight loss. Diarrhoea had also developed a month before presentation. Abnormal clinical findings were emaciation, diarrhoea, ventral oedema, palpable mesenteric lymph node enlargement and a large mass in the left cranial portion of the abdomen. Significant laboratory findings were anaemia (packed cell volume 0.21 litres/litre), hypoalbuminaemia (16 g/litre) and xylose malabsorption. The horse was euthanased and at necropsy a 10.5 kg pendunculated mass composed of granulation tissue was found within and attached to the stomach. There was villous atrophy diffusely throughout the small intestine. The inciting cause of the gastric mass was not determined.
