Intestinal metastases from lung cancer

Introduction Intestinal metastasis from primary lung cancers is rare and usually asymptomatic. Case report We report two cases of symptomatic small bowel metastasis. The first one presented with a persistent anaemia occurring in a 54 year old man who had undergone a left lower lobectomy for a large cell carcinoma. The second case was a 75 year old man who presented with peritonitis which led to discovery of a lung primary. Conclusion Intestinal metastasis can be the presenting feature of, or complicate lung cancer. Symptomatology depends on metastasis localisation. Their treatment is difficult and they are associated with a poor prognosis.
