title: [A case of perforated metastatic small intestine tumor from the lung].
abstract: We report a case of perforated metastatic small intestine tumor from the lung. A 56-year-old male admitted for lung cancer with multiple distant metastases developed severe epigastralgia. As radiographic examination revealed free air below diaphragm, we have suspected perforation of upper digestive tract. Exploratory laparoscopy carried out the next day demonstrating perforation of proximal jejunum. Despite jejunal resection, the patient has died of respiratory failure. Pathological evaluation of resected intestine showed a metastatic jejunal tumor with perforation. Metastatic tumor in the digestive tract from lung is a rare condition, and it usually occurs as a part of systemic involvement. To achieve an early diagnosis and treatment, perforation of metastatic tumor should be taken into notice.
