A Case of Multiple Primary Lung Cancers with a Solitary Bronchogenic Papilloma and Laryngeal Cancer

Abstract

A 68-year-old man was admitted to our hospital for further evaluation of a left hilar shadow on chest X-ray. He had smoked 12 cigarettes/day for 50 years. Bronchoscopic findings showed obstruction of left B^6 with a tumor and polypoid lesion of the spur of left B^3. Histological study showed that both were squamous cell carcinoma. Since no metastasis was detected, left pneumonectomy was performed. The tumor in left B^6 was 4.5cm in diameter and was diagnosing histologically a differentiated squamous cell carcinoma. Polypoid lesion in left B^3 was carcinoma in situ. None of the dessected lymph nodes were involved. We diagnosed this case as multiple primary lung cancer. We found a solitary bronchogenic papilloma in left B^8 of the resected lung. After two years laryngeal cancer was detected.
