Lipomas are benign submucosal tumors composed of mature adipose tissue. Some authors have described patients with persistent abdominal pain who were misdiagnosed as intestinal adenocarcinoma and the diagnosis turned out to be a lipoma on histological examination. We discuss the case of a 57-year-old woman presenting with abdominal pain for 4 weeks. Intestinal adenocarcinoma was found by double-balloon enteroscopy (DBE), but at first only lipoma was found by CT scan. Therefore we want to emphasize that lipoma should not always be regarded as pseudomalignant features, sometimes lipoma conceals intestinal adenocarcinoma, and DBE may be a better way to discover malignancy.
脂肪瘤是由成熟脂肪组织构成的良性黏膜下肿瘤。一些作者描述过，有持续性腹痛的患者被误诊为肠道腺癌，而组织学检查结果却是脂肪瘤。我们讨论一例57岁女性，她有4周的腹痛症状。双气囊小肠镜检查（DBE）发现了肠道腺癌，但最初CT扫描仅发现了脂肪瘤。因此，我们想强调，脂肪瘤不应总是被视为假恶性特征，有时脂肪瘤会掩盖肠道腺癌，而DBE可能是发现恶性肿瘤的更好方法。
