Early gastric cancer with psammomatous calcification.
We describe a 51 year-old man with calcified early gastric cancer. The calcification was not displayed by abdominal X-ray, CT, or conventional ultrasound. Only endoscopic ultrasonography displayed the distribution of calcification in vivo. Endoscopic ultrasonography revealed a slightly hypoechoic lesion with a high echoic line, without involvement of the fourth layer. Histopathologically, it was a IIc type early gastric cancer. The depth of cancer invasion was limited to the mucosa and a mucin pool was not observed. Psammomatous calcification was observed in the lumen of the carcinomatous glands. This seems to be the first case reported in which psammoma bodies were observed in early gastric cancer.
