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.
我们描述了一名患有钙化性早期胃癌的51岁男性。腹部X线、CT或传统超声均未显示钙化情况。只有内镜超声在体内显示了钙化的分布。内镜超声显示一个略低回声病变，伴有高回声线，未累及第四层。组织病理学检查显示为IIc型早期胃癌。癌症浸润深度局限于黏膜层，未观察到黏液池。在癌性腺管腔内观察到砂粒体钙化。这似乎是首例报道的早期胃癌中出现砂粒体的病例。
