A colonoscopic examination of a 58-year-old man revealed a small elevated lesion inside the orifice of the appendix. Using a polypectomy snare, a nodular polypoid lesion with a diameter of ca. 20 mm was removed from the lumen of the appendix. Histopathology showed that it was a well-differentiated adenocarcinoma. This is the first report of an intramucosal adenocarcinoma of the appendix diagnosed preoperatively; laparoscopy-assisted colectomy with a D2 lymph-node dissection was carried out. Endoscopists should consider an appendiceal tumor when an erosion, elevation, or deformity is seen in the head of the cecum.
对一名58岁男性进行结肠镜检查时，发现阑尾开口处有一个小的隆起病变。使用息肉切除圈套器从阑尾腔内切除了一个直径约20毫米的结节状息肉样病变。组织病理学显示为高分化腺癌。这是术前诊断出的阑尾黏膜内腺癌的首例报告；实施了腹腔镜辅助结肠切除术并进行D2淋巴结清扫。当在盲肠头部看到糜烂、隆起或畸形时，内镜医师应考虑阑尾肿瘤。
