Intussusception is the second most common abdominal emergency in children. On the contrary, it is rare in adults. Most of adult intussusceptions are caused by definable structural lesions, and about half of these lesions are malignant. However, intussusception caused by gastrointestinal metastasis from lung pleomorphic carcinoma is extremely rare, and only a few case reports have been published thus far. We present a rare case of gastrointestinal metastasis from lung pleomorphic carcinoma causing jejuno-jejunal and colon-colonic intussusceptions, and review the previously 3 published cases. Intussusceptions caused by gastrointestinal metastases should always be considered in the differential diagnosis of patients with lung pleomorphic carcinoma presenting with gastrointestinal symptoms. Metastasis-related intussusception is a poor prognostic indicator in patients with pleomorphic carcinoma, regardless of the treatment.
肠套叠是儿童第二常见的腹部急症。相反，在成人中却很少见。大多数成人肠套叠是由可明确的结构性病变引起的，其中约一半病变是恶性的。然而，肺多形性癌引起的胃肠道转移导致的肠套叠极为罕见，迄今为止仅有少数病例报告发表。我们报告一例罕见的肺多形性癌胃肠道转移导致空肠-空肠和结肠-结肠套叠的病例，并回顾此前发表的3例病例。对于出现胃肠道症状的肺多形性癌患者，鉴别诊断时应始终考虑胃肠道转移引起的肠套叠。无论采用何种治疗方法，转移相关的肠套叠在多形性癌患者中都是预后不良的指标。
