A Case of the Triple Primary Squamous Cell Carcinoma of the Lung with a Spontaneous Disappearnce of the Third Tumor

Abstract

A 67 year-old man was admitted to our hospital with bloody sputumn. Chest roentgenogram was normal, but Bronchoscopic examination revealed a carcinoma of right upper lobe bronchus. On June 21, 1983, sleeve upper lobectomy was peformed. Eight months later, a second carcinoma developed at right B^<10>, and pneumonectomy was performed. On May, 1985, a third polypoid carcinoma was developed at left B^<1+2>, but cancer therapy was not instituted because of complications. A year later, follow-up bronchoscopy demonstrated the absence of the tumor, and brushing cytology was negative.
