The Usefulness of a Simple Classification for Bronchoscopic Findings for Diagnosis of Peripheral Pulmonary Tumour.

Background: Normal bronchial epithelium has been described in terms of transparency and smoothness. No studies have compared bronchoscopic and pathological findings in the identification of bronchial epithelium.

Objectives: This study aimed to classify bronchoscopic findings for peripheral pulmonary tumour (PPT) for accurate bronchoscopic diagnosis accounting for the presences of bronchial epithelium and bronchial stenosis using an ultrathin bronchoscope.

A 74-year-old woman was admitted to our hospital for further examination of chest X-ray abnormality. The chest computed tomography (CT) revealed a nodular lesion (1.0 cm in diameter) in right lung.

A 66-year-old female complained of cough, and was referred to our hospital. Chest radiography and computed tomography (CT) showed a tumor mass near the right hilum and atelectasis of the middle lobe. Bronchoscopy revealed a whitish polypoid tumor obstructing the middle lobe bronchus.
