Multiple minute cancers of major bronchi. A case report.

A case with early lung cancers of the major bronchi was reported. Three separate minute foci of carcinoma were found in the major bronchi of the resected specimen which appeared unrelated to foci of atypical metaplasia or dysplasia. About 2 years after bilobectomy the patient died of carcinoma of the esophagus which was considered to be an independent primary carcinoma.
