We describe a case of gastric lymphangioma coexisting with mucosal gastric cancer. A 76-year-old man was diagnosed with an advanced gastric cancer (cT2N0M0, Stage I) presenting a nodular protruded lesion with irregular central depression. The surgically resected specimen showed a 4 × 3 cm sessile protruded lesion in the anterior wall of the lower stomach. Histopathological examination revealed a mucosal adenocarcinoma was located immediately above the lymphangioma and was elevated by the cystic component of lymphangioma without admixture, which suggested that the two components arose separately. The mucosal adenocarcinoma was masquerading as an advanced gastric cancer due to the protrusion by the lymphangioma.
我们描述了一例胃淋巴管瘤与胃黏膜癌共存的病例。一名76岁男性被诊断为进展期胃癌（cT2N0M0，Ⅰ期），表现为有不规则中央凹陷的结节状突出病变。手术切除标本显示胃下壁前壁有一个4×3 cm的无蒂突出病变。组织病理学检查显示，黏膜腺癌位于淋巴管瘤正上方，并被淋巴管瘤的囊性成分抬高，两者无混合，提示这两个成分是分别发生的。由于淋巴管瘤的突出，黏膜腺癌伪装成了进展期胃癌。
