Among 2, 336 cases of primary gastric carcinoma and 518 cases of large intestinal carcinoma, resected between 1955 and 1972 at Tokyo University Hospital, there were 115 cases (4.9%) of mucinous carcinoma of the stomach and 41 cases (7.9%) of mucinous carcinoma of the large intestine.Clinical and pathohistological studies of these mucinous carcinoma were made and the following results were obtained.1. Age and sex incidence of mucinous carcinoma of the stomach was much the same as overall gastric carcinoma. Female cases of mucinous carcinoma of the large intestine were more common than male while male cases were more common than female in the overall large intestinal carcinoma.2. Mucinous carcinoma was classified into three groups according to histological structural differentiation i.e. well differentiated, moderately differentiated and poorly dif-ferentiated group. The poorer the differentiation of mucinous carcinoma, the younger the mean age in both stomach and large intestine. Mean age of poorly differentiated group of large intestinal mucinous carcinoma was very young: 33.2 years of age.3. It was confirmed that presence of metastasis to regional lymph node, depth of infiltration to the wall and grade of structural differentiation had influence on the prognosis of mucinous carcinoma of the stomach. Prognosis of mucinous carcinoma of the colon was much better than that of the rectum.
