Twelve cases of scirrhous type carcinoma were studied in order to investigate their endoscopic ultrasonographic findings. The ultrasonogram of scirrhous type carcinomas was observed the five ultrasonic layers resembling that of the normal gastric wall. The length from the first layer to the fourth layer and the thickness of the fourth layer were measured near primary foci in nine resected scirrhous type carcinomas. And they were also measured at non-cancerous portions in 13 resected stomachs as a control. The length was 13.8±2.5 mm and the thickness was 6.2±1.3 mm in scirrhous type carcinomas. But the length was 4.3±0.6 mm and the thickness was 1.0±0.3 mm in non-cancerous portions. Accordingly the gastric wall of the scirrhous type carcinoma was significantly thicker than that of non-cancerous portions. Furthermore the echoic pattern of the third layer was slightly hypoechoic than in usual, and that of the fourth layer showed as low echoic pattern with high echoic spotts. These findings were obviously different from those of medullary type carcinoma, hypertrophic gastritis or malignant lymphoma. Fibrosis accompanied by the scirrhous type carcinoma was thought to play an important role in the findings of the ultrasonic echogram. The scirrhous type carcinoma will come to be detected in the earlier stage by the endoscopic ultrasonography.
