Solitary bronchial papilloma presenting with recurrent dyspnea attacks: case report with computed tomography findings.

A case of solitary bronchial papilloma is reported which, because of its unusual location near the carina and marked mobility, presented with attacks of dyspnea that were misdiagnosed as asthma for many years. It caused no abnormality on a plain chest X-ray, but could be visualized on linear and computed tomograms. The computed tomograms further demonstrated the absence of extraluminal extension of the tumor or mediastinal lymphadenopathy which could not be excluded by linear tomography or bronchoscopy. Transbronchial resection resulted in complete relief of symptoms.
