Abstract:
Esophageal carcinoma was observed in an eight-year-old, castrated male, Japanese domestic cat. Histologically, this neoplasm consisted of two different growth patterns, squamous cell carcinoma and adenocarcinoma. The results of immunohistochemical examination supported the fact that the two kinds of neoplastic cells have different characteristics. The tumor was, therefore, diagnosed as adenosquamous carcinoma. Esophageal tumors in the cat are very rare and, if any, neither adenocarcinoma nor adenosquamous carcinoma has been reported up to the present.
