Diagnosis of stomach carcinoma in the horse.

In 10 horses, which were referred to the clinic with the suspicion of disor ders of the gastrointestinal tract, gastroscopy revealed a gastric tumour. In ten cases the diagnosis of a squamous cell carcinoma was made on the bas is of histology of biopsies or autopsy. The tumour always derived from the non-glandulary mucosa. The horses showed various clinical symptoms. All pat ients had a hypoalbuminemia and a hyperglobulinemia in the serum electropho resis. This suggests that a gastric tumour can be suspected intra-vitam eve n without gastroscopy of the patient.
