Bronchial papilloma is a rare disease which most commonly manifests as an epithelial tumor consisting of polypoid interstitial tissues and epithelioid cells. This benign tumor comprises 2-5% of primary lung tumors and papilloma derived from the bronchial epithelium, and is a rare benign tumor in adults. Bronchial papilloma has a poor prognosis with a high risk of developing a malignancy. We report a case of a bronchial papilloma in a 62-year-old female patient, presenting with hemoptysis and an endobronchial lesion with a brief review of the relevant literature.

Benign papillary tumors commonly arise in the upper respiratory tract but are rare in the lower respiratory tract, especially in the bronchi. Solitary benign papillary tumors arising at the bronchi,covered with stratified squamous epithelium and associated with little or no inflammatory cell response,seem to be rarest of all types of benign bronchial tumors. Only six cases of such tumors had been reported in the medical literature over the past 74 years until 1968. The following is a case report of solitary benign papilloma arising at the opening of the left main bronchus which was treated with bronchoscopic removal at Chest Surgery Depariment, N.M.C. on Sept.

Pulmonary papillomas are rare benign epithelial neoplasms arising in bronchial surface epithelium. They are categorized by a variety of cell types including squamous, glandular, and mixed squamous and glandular type. Among them, glandular papilloma is extremely rare and has not been reported in Korea. The patient was a 52 year-old man presenting with a 4-months' history of recurrent hemoptysis. Bronchofiberoscopy revealed a whitish, glistening, and polypoid mass lesion at the proximal bronchus in the basal segment of the left lower lung. Bronchoscopic biopsy was performed; papillary fronds lined by ciliated or nonciliated pseudostratified columnar epithelium were noted on histologic findings. We present the first case of glandular papilloma in Korea. Two years later, the patient visited our hospital again due to hemoptysis. On follow-up bronchoscopy, a mass that had been found previously showed an increase in size.

A 59-year-old woman was admintted to the hospital because of intermittent fever and right side chest pain. She has a same episode eight months before this entry. Chest CT scan demonstrated ill-defined parenchymal consolidation containing dilated bronchi of right lower lung field, but no endobronchial mass in the bronchial trees. Fiberoptic bronchoscopy seeking the cause of recurrent pneumonia revealed a small, round mass nearly completely obstructing me lumen of basal segmental bronchus of right lower lobe. The diagnosis of bronchiolar papilloma was made from the biopsy specimens of the bronchoscopic examination. The patient was treated with right lower lobectomy because of irreversible secondary changes below the obstructed bronchus. This thoracotomic excision resulted in complete relief of symptoms and the postoperative course was uneventful for 12 months. Here we report a extremely rare umor with a brief review of literatures.
