Single intestinal metastasis of non-small cell lung carcinoma.

A 60-year-old man with a history of hypertension and hypercholesterolemia, former smoker, gastric ulcer 5 years earlier, non-small cell lung cancer (T1N0M0) diagnosed and treated surgically (lobectomy without adjuvant therapy) 15 months before, was admitted with symptoms of dizziness, hypotension, melena and epigastric pain. A blood test performed at admission showed anemia (7.3 g/dL hemoglobin), low mean corpuscular volume (76 fL), slight thrombocytosis and normal leukocyte count; renal function, electrolytes and transaminases were normal. The patient improved clinically after transfusing three units of packed red cell and then, an upper endoscopy was performed without appreciating lesions in the esophagus, stomach and duodenum. Because of the persistence of anemia in subsequent analytical tests, scheduled colonoscopy was performed that showed no injury to the hepatic flexure. Selective arteriography (Fig. 1) was performed, which showed a bleeding lesion in the small intestine (jejunum) that was surgically resected few days later. The histopathological study of the specimen
