A Case of Small Cell Carcinoma of the Lung with Metastasis to the Stomach

A 64 year-old man complained of chest pain, cough and occasional hemosputum. His cigarette index was 1075. The chest roetgenogram showed a large tumor-like shadow in the right hilum. Sputum cytology and bronchoscopic biopsy of the tumor in the right truncus intermedius showed small cell carcinoma. A radiographic examination of the upper gastrointestinal tract was made because the stool was positive for blood and anemia was progressing. A large ulcerated mass on the greater curvature and a non-ulcerated mass on the lesser curvature of the stomach were found. Gastroscopic biopsy of the ulcerated mass showed small cell carcinoma identical to the bronchoscopic biopsy. The patient was treated with chemotherapy with complete respnse, but he died 26 months later from widespread liver metastasis. Clinically apparent gastric metastases from carcinoma of the lung are extremely rare.
