Six cases of squamous cell carcinoma of the stomach of the horse.
Six cases of squamous cell carcinoma of the stomach in horses seen at the New York State College of Veterinary Medicine are compared with 15 similar cases reported previously. Clinical signs included anorexia in all cases, emaciation, fever, anaemia and/or palpable abdominal masses in 3, colic in 2 and dysphagia in one case. Haematological studies revealed normochromic, normocytic anaemia in 3 and absolute neutrophilia in 5 cases. Peritoneal fluid analysis was performed in 4 cases and revealed slightly to moderately elevated total protein concentrations in 3 and a markedly elevated number of white blood cells in 2 cases. Exploratory laparotomy, performed in 3 cases, was essential for a definitive diagnosis. The data presented here suggest that squamous cell carcinoma of the equine stomach may be increasing in frequency and demonstrate the need for prospective epidemiological studies.
