Esophageal squamous cell carcinoma in two cats.

Esophageal carcinomas in two cats are described. The main clinical sign was regurgitation of food and fluids. Radiographic examination revealed severe esophageal abnormalities in both cats. In the second cat, the radiographic appearance of the esophagus together with the esophagoscopic findings provided a presumptive diagnosis of neoplasia. Histologic examination in both cats revealed squamous cell carcinoma with metastases.
