title: Adult jejunojejunal intussusception caused by metastasized pleomorphic carcinoma of the lung: report of a case.
abstract: Adult small-intestinal intussusception is rare and very different from childhood intussusception. Both benign and malignant pathologies can underlie small intestinal intussusception in adults, but malignancy is much less frequent. We report a case of jejunojejunal intussusception caused by an intestinal metastasis of the sarcomatoid component of pleomorphic carcinoma of the right lung. The patient, a 61-year-old man, underwent successful segmental jejunal resection. Adult small bowel intussusception, though an unusual cause of acute abdomen, requires early diagnosis and timely management. To our knowledge, this is the first report of adult jejunojejunal double intussusception caused by metastatic sarcomatoid carcinoma of the lung.
