Endobronchial Polyp

Abstract

A case of benign endobronchial polyp is reported. The unusual feature is that the major signs and symptoms, consisting of dyspnea, absence of breath sounds in one lung, and massive atelectasis of the same lung at roentgenologic examination, occurred suddenly. A “polyp,” exactly duplicating the structure of the benign nasal polyps, was removed at endoscopy, with immediate relief of symptoms and return to normal conditions. In the absence of any history of chronic inflammatory disease of the respiratory tract and in the light of the microscopic structure of the polyp showing prominent edema and congestion, it is assumed that the endobronchial lesion resulted from a progressive accumulation of edema fluid in the bronchial mucosa, ultimately giving rise to massive mucosal herniation and bronchial occlusion.
