The appearance of adenosquamous structures in cancer of the stomach was studied in 385 resected specimens. Such structures were observed in 9.1% of the specimens. However, they were not found in cases in which the invasion was limited to the mucosa. The frequency of the appearance increased in correlation with the extent of the cancerous invasion. The type of adenocarcinoma that coexisted with the squamous changes was the intestinal type of Lauren in 68% of the specimens. This indicates that the squamous structures, seen in gastric cancer result from secondary metaplasia of the intestinal type in this condition.
