Colonic Metastases From Lung Carcinoma: A Case Report and Review of the Literature

Ana Isabel Gonzalez-Tallon, Jorge Vasquez-Guerrero, Maria Angeles Garcia-Mayor


Lung cancer is the most frequent cause of cancer death in the world. Although about 50% of lung cancers have distant metastases at the time of diagnosis, gastrointestinal metastasis has rarely been described. The most common metastatic site is the small bowel, whereas, colonic metastases are very rare. This report presents a clinical case of a 68-year-old male with a previous diagnosis of non-microcytic lung carcinoma (T4, N2, M1), stage IV, who presented rectorrhagia at the emergency. Colonoscopy showed many ulcerated tumors along the colon and histology proved that these lesions were metastases of primitive lung carcinoma. Gut metastasis from the lung is uncommon but we have to be aware of it in patients who present gastrointestinal symptoms.
