A 81-year-old male with primary squamous cell carcinoma of the lung was admitted because of melena. Upon autopsy, bleeding sites were found in the small and large bowel; they were lesions from the lung carcinoma. Gastrointestinal metastases from primary lung carcinoma are clinically rare, although they are seen in autopsy cases. Review of autopsy data on 1181 cases of primary lung carcinoma showed that 218 (18.5%) manifested gastrointestinal metastases.
