Lipomas of the large intestine are uncommon tumour. They are often innocuous and do not cause any clinical problem, particularly if they are small (<2 cm) is size. However, they can give rise to significant clinical symptoms if they become large and can be mistaken for colorectal carcinoma. Herein, a giant submucosal lipoma of descending colon is described, which was preoperatively suspected of carcinoma and underwent left hemicolectomy. The diagnosis was only reached after pathological examination of the resected tumour. The case highlights that a large colonic lipoma still poses diagnostic difficulty. Accurate diagnosis of the lipomas is important as they can be removed by endoscopic polypectomy or segmental resection, obviating the need of unnecessary major surgical resection.
大肠脂肪瘤是一种不常见的肿瘤。它们通常是无害的，不会引起任何临床问题，尤其是如果它们很小（<2cm）。然而，如果它们变得很大，它们可能会引起显著的临床症状，并可能被误诊为结直肠癌。本文描述了一例降结肠巨大黏膜下脂肪瘤，术前怀疑为癌，并接受了左半结肠切除术。只有在对切除肿瘤进行病理检查后才能做出诊断。该病例强调了大型结肠脂肪瘤仍然存在诊断困难。准确诊断脂肪瘤很重要，因为它们可以通过内镜息肉切除术或节段切除术切除，避免了不必要的大手术切除。
