Abstract

A 72-year-old man underwent a right upper lobectomy for squamous cell carcinoma on December 5, 1991.
In November, 1994, a chest X-ray revealed a mass shadow in the right lower lung field, and bronchoscopy revealed a polypoid tumor in the right lower bronchus. Right lower lobectomy was performed. Histopathological examination showed tubular adenocarcinoma with intraluminal polypoid growth origination in the right lower bronchus.
This is a rare case of metachronous double lung cancer : a peripheral squamous cell cancer in the right upper lobe and adenocarcinoma with intraluminal polypoid growth in the right lower bronchus.
