Colonic metastasis from squamous carcinoma of the lung: report of a case and review of the literature.

We describe a rare case with metastatic involvement of the gastrointestinal tract (colonic metastasis) secondary to lung cancer. After diagnostic work-up, a left hemicolectomy was performed. Patient has been alive and healthy 9 months after operation. We report the first case with the longest survival period after the diagnosis of metastasis, although the symptomatic gastrointestinal metastases from lung cancer generally follow a poor prognosis because of their advanced state and multiplicity.
