title: [A case of double neoplasms--small cell carcinoma in the mediastinum and squamous cell carcinoma of the esophagus].
abstract: A 62-year-old Chinese man was admitted to our hospital because of dysphagia and hoarseness. Chest X-rays showed a superior mediastinal mass, and an operation for the removal of this mediastinal tumor was performed. The histological diagnosis indicated a small cell carcinoma, probably arising from the lung. He was readmitted to our clinic one year later with a complaint of dysphagia due to an esophageal cancer. Radical surgery for the esophageal cancer was performed, and the histological findings showed a well differentiated squamous cell carcinoma. The histogenesis of this carcinoma was considered to be independent of the earlier mediastinal tumor.
