[Jejuno-jejunal intussusception as presentation of a primary lung carcinoma: a case report].

Intestinal metastases from lung cancer are exceptional and even more rare is their manifestation before the primary tumor. The clinical manifestation may require surgical resection because of intestinal perforation, hemorrhage, intestinal obstruction or partial blockage as in the case that we report. Survival in the few cases reported, is low and generally does not exceed 20 weeks, regardless of the treatment performed. We report the case of a jejuno-jejunal intussusception manifested by occlusive syndrome and gastrointestinal bleeding due to the metastasis of an adenosquamous lung carcinoma.
