A 64-year-old man was hospitalized because of pneumonia. After the pneumonia was resolved by administration of antibiotics, a tumor-like shadow was noted in the superior portion of the hilus of the left lung on chest X-ray and bronchoscopy was performed. Tumors were observed at four positions ; right B^2, right B^6, left B^<1+2>, and the left basal bronchus. All were proven to be well differentiated squamous cell carcinoma by biopsy. All four tumors were polypoid tumors projecting into the bronchial lumen and showed similar appearance and were not continuous. Therefore this case was diagnosed as primary quadruple lung cancers. We considered that surgery was not indicated so we conducted chemotherapy. As a result, remission of all four tumors was obtained and the patient is alive at present.
