title: Gastrointestinal hemorrhage and small cell carcinoma.
abstract: Despite widespread dissemination of primary lung carcinoma by lymphangitic and hematogenous routes, acute gastrointestinal signs and symptoms are rarely presenting symptoms for bronchogenic carcinoma. We present a patient with small cell carcinoma of the lung who came to medical attention because of a lower gastrointestinal hemorrhage. In the absence of radiographically apparent pulmonary disease, the correct diagnosis was suggested by the biopsy specimens of the colon.
