有人主张，为了确定结肠腺癌之前的粘膜病变类型，仅应考虑直径<1mm的肿瘤。英文文献的审查表明，只有35个大肠腺癌测量直径为10.1厘米到目前为止已报告。本文报告的3例直径小于或等于8 mm的结肠腺癌中，1例起源于扁平腺瘤，1例起源于外生管状腺瘤，3例无腺瘤成分。因此，结肠腺癌不仅可以起源于外生性腺瘤或扁平腺瘤，而且也可以起源于表面上非腺瘤性的扁平粘膜。© 1994 Wiley利斯公司
It has been claimed that in order to identify the type of mucosal lesion which precedes colonic adenocarcinoma only those tumours measuring ⩽1 mm in diameter should be considered. The review of the English literature indicates that only 35 colorectal adenocarcinomas measuring ⩽1 cm in diameter have been so far reported. From the three cases of colonic adenocarcinoma measuring 8 mm or less in diameter presented here, one adenocarcinoma originated in a flat adenoma, the second in an exophytic tubular adenoma, and the third showed no adenomatous component. It would thus appear that colonic adenocarcinomas can originate not only from exophytic adenomas or from flat adenomas but also from apparently nonadenomatous flat mucosa. © 1994 Wiley‐Liss, Inc.
