[A clinicopathological study of five cases of adenosquamous carcinoma of the stomach]

Five cases of adenosquamous carcinoma with resected stomach were subjected to this study, and the clinicopathological characteristics of this condition were described. The five patients represented 0.8% of 589 cases of resected stomach. There were two men and three women ranging in age from 40 to 70 (average, 62.8). Macroscopically, the adenosquamous carcinomas were all advanced gastric cancer situated in the lower body along the lesser curvature of the stomach, averaging 7.6 cm in size. The characteristic finding was the histologically differentiated type, invading to the serosa. Lymph node metastasis was most prominent.
