A 69-year-old man was admitted complaining of bloody sputum. A chest X-ray and CT revealed no abnormal findings, but bronchoscopy revealed a squamous cell carcinoma nodular lesion in the bifurcation between the left B(1+2)a and B(1+2)b. After two courses of chemotherapy (CBDCA + PAC), the nodular lesion disappeared. Another nodular squamous cell carcinoma grew in the orifice of the left B(1+2) nine months later, but this time chemotherapy was ineffective. The nodular tumor was cauterized twice with argon plasma coagulation, and no recurrence appeared for twenty-six months.
