Carcinoma of the bronchus with atypical presentation: report of a case.

A 64-year-old man presented with dysphagia due to obstruction of lower third of the esophagus. Esophagoscopy showed narrowing of the esophagus with normal mucosa. Chest X rays were normal, but on lung scan there was no perfusion of the left lung. That patient died of aspiration and on post mortem a carcinoma of the bronchus with abscess formation and perforation into the esophagus was found.
