title: [Two surgical cases of synchronous double carcinoma of the lung and esophagus and review of 10 documented cases in Japan].
abstract: Synchronous double carcinoma of the lung and the esophagus is extremely rare disease. In Japan, 13 cases have reported by Abo and only 10 clinical cases have been documented so far. We describe two cases of synchronous double carcinoma of the lung and the esophagus. Case 1. A 74-year-old man was admitted to our hospital because of the abnormal shadow of the chest X-ray film. Left upper lobectomy was carried out for the lung carcinoma. Because of dysphagia after surgery, upper GI series and endoscopic biopsy were performed, and midesophageal carcinoma was revealed. Radical operation of the esophageal carcinoma was performed 2 months after the first operation. Pathological diagnosis of the lung tumor and the esophageal tumor were well differentiated adenocarcinoma and moderately differentiated squamous cell carcinoma respectively and both of them were early cancer. After 22 months of the second operation, he is doing well. Case 2. a 66-year-old man was operated on because of the esophageal carcinoma in other hospital. Abnormal shadow appeared in his X-ray film 10 months after operation. Although he received chemotherapy as metastatic lung cancer, bronchoscopic examination revealed it adenocarcinoma. We performed segmental lobectomy to him 17 months after the first operation. Pathological diagnosis was large cell carcinoma of the lung. He is also doing well 18 months after the second operation.
