Abstract

Two cases of stomach mass and one case of tongue mass were observed in Japanese monkeys(Macaca fuscata) which were raised in Yong-in Farm Land. Histologically, two spontaneous tumors were found in the cardiac region of the stomach and were diagnosed as squamous cell carcinoma. These tumors had invaded the submucosa, muscular layer and serosa, but metastasis was not found in the other tissues including the lymph node. One spontaneous tongue mass was diagnosed as squamous cell carcinoma.
