RESUMO
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.

The Japan Mammary Cancer Society's General Rules for Pathological Record prescribe differential diagnosis of the noninvasive or invasive status of human breast cancer upon discovery of basement membrane. We discovered basement membranes not only in normal mammary glands and non invasive breast cancers, but in metastatic breast cancers to the lungs and regional axillary lymph nodes. We concluded that, for such diagnosis, it is necessary to observe the cellular arrangement and condition of the surrounding stromal tissues with light microscopy. Nuclear chromatin patterns should also be examined; they showed predominantly euchromatin in invasive breast cancer and heterochromatin in non-invasive breast cancer with electron microscopy.
