Large-cell carcinoma of the lung. With major bleeding and intussusception.

We describe an unusual case of major small-bowel bleeding and intussusception due to jejunal metastases from a large-cell type carcinoma of the lung. Review of the surprisingly frequent case reports of small bowel metastases from primary lung tumors indicates that there is only one prior case report of intussusception and that ours is the first description of major intestinal hemorrhage due to metastatic pulmonary carcinoma.
