Abstract
Lipomas of the colon are submucosal nonepithelial tumours covered by intact or eroded mucosa. A large colonic lipoma present in close proximity to an area of diverticulitis is presented. The lining mucosa in this case exhibited hyperplastic changes, reminiscent of those seen in hyperplastic polyps. The significance of such mucosal changes are highlighted because adenomatous or even carcinomatous transformation, though rare, remains possible.
摘要
结肠脂肪瘤是被完整或糜烂黏膜覆盖的黏膜下非上皮性肿瘤。本文报告一例位于憩室炎区域附近的巨大结肠脂肪瘤。该病例中的衬里黏膜呈现增生性改变，类似于增生性息肉所见的改变。此类黏膜改变的意义得到了强调，因为腺瘤性甚至癌性转化虽然罕见，但仍有可能发生。
