[Colonic metastasis from primary carcinoma of the lung. Case report].

Lung cancer is the most common cause of cancer-related death in both men and women in Western countries. About one-half of patients with lung cancer have metastatic disease at the time of initial diagnosis. Metastasis to the gastrointestinal tract from primary lung cancer has rarely been described. The most common metastatic site is the small bowel whereas large bowel secondary lesions are very rare. The majority of patients are referred to a surgeon only after the intestinal secondary lesion becomes symptomatic posing a threat to the patient's life. Although the outcome is still unfavourable, the development of chemotherapy and of surgical techniques allows aggressive treatment when facing a single intestinal metastasis from lung cancer. We report on a case of a patient who came to our observation for a neoplastic stenosis of the descending colon with a single liver secondarism. Histology proved both lesions to be metastases of primitive adenocarcinoma of the lung.
