ORUEZABAL MORENO, M. J.; BURON FERNANDEZ, M. R.; LOPEZ-DORIGA, R. Lara    ESPINOSA AUNION, R.. Jejunum invagination by intestinal metastasis from a primary lung carcinoma: report of a case and review of the literature. []. , 29, 9, pp.43-47. ISSN 0378-4835.

Intestinal metastases from primary lung carcinoma are of rare presentation, and exceptionally, can appear before the primary tumor manifestations. The diagnosis is based on the expression of some cytokeratins and specific lung markers, as TTF-1. Obviously, although focusing on the treatment of the metastatic lung cancer, a surgical intestinal resection in case of perforation, intestinal hemorrhage or obstruction is mandatory, as it happened in the case we report. According to the few published cases, survival is poor, not surpassing 20 weeks in spite of treatment. We present a case of intestinal intussusception caused by metastases from a primary anaplastic carcinoma of the lung.
