A solitary papilloma of the left main bronchus in a 48 year old man is described. The patient had a one year history of cough, hemoptysis and bronchospasm. Bronchoscopy and repeated removal of the tumour through the bronchoscope failed to control it, and local recurrence finally made pneumonectomy necessary.

Juvenile laryngotracheal papillomatosis spreads to involve the lungs in less than 1% of cases, and when this occurs, the prognosis is poor. In seven such cases, the lung lesions, which appeared either solid or cystic on radiographs, proved to be benign squamous cell proliferations or papillomas, with central cavities containing debris or air. They seemed to grow centrifugally, using the alveolar walls as scaffolding with central coalescence and lung destruction. Papillomas spread inferiorly from the larynx by direct extension as far as the major bronchi, but rarely beyond. However, the parenchymal lesions were widely scattered, and some were subpleural. This discrepancy suggests that fragments become detached, particularly during endoscopic resection, and are carried down the airways by airflow. Those that lodge proximal to the respiratory bronchioles may be removed by mucociliary action and cough. Those that travel more distally are poorly cleared and may grow. If enough lung parenchyma is destroyed, the patient can develop symptoms of restrictive lung disease in addition to signs of upper airway obstruction.

Topical chemotherapy with the antimetabolite 5-fluorouracil (5-FU) has been used as an adjunct to surgical laser excision of squamous papillomas arising in the larynx and in the tracheobronchial tree. The drug has been administered intensively to eight patients with tracheotomies and disease in both anatomic regions. These patients received repeated instillations of 5-FU at concentrations from 0.5 to 5% into the larynx and tracheobronchial tree while in the hospital and at home. More than 4,500 doses of the drug have been administered during our phase 1 study. There has been no significant toxicity associated with repeated 5-FU instillation into the airway. Several patients developed blood-tinged tracheal secretions after the repeated use of high concentrations of the agent. Other complications included coughing, bronchospasm, and peristomal irritation. These symptoms all disappeared after temporary discontinuation of the drug. No patient has developed a systemic hypersensitivity response to the drug either detectable clinically or by repeated skin testing. There were no adverse effects on the hematologic or hepatic systems. Use of 5-FU was associated with inhibition of papilloma regrowth in six of eight patients. The major limitation to drug effectiveness is the requirement for its frequent administration.

Upper airway obstruction is well described as a cause of apparent asthma. However, it can be very difficult to diagnose in young children. This 3-year-old male presented with a 1-year history of severe recurrent wheezing with six emergency room visits in the previous 5 months. Cromolyn, inhaled corticosteroids, and frequent predinisolone bursts had not controlled the wheezing. There was no history of barky cough, croup, or stridor. His physical examination was notable for marked nasal obstruction. At initial presentation, his lungs were normal with no wheezing or stridor. Soft tissue neck X-ray films suggested the presence of a subglottic mass. A large solitary papilloma was found on bronchoscopy. After surgical removal, there was no further wheezing noted by either the parents or his physicians. Laryngeal papillomatosis may mimic asthma in the absence of symptoms of hoarseness, croup, or stridor. It should be particularly considered in 2 to 4-year-old children with recurrent wheezing that is poorly responsive to aggressive therapy including oral corticosteroids.

A 79-year-old female presented with persistent dry cough, and a chest radiograph showed a mass shadow in the right upper lung. Bronchoscopic examination revealed that the right main bronchus was severely obstructed by a polypoid tumor, which was diagnosed pathologically as squamous papilloma. After the failure of the attempted endobronchial snare to remove the tumor, right upper lobectomy was performed. The polymerase chain reaction (PCR) examination showed the presence of human papilloma virus type 11 DNA in the resected tumor, suggesting that this virus was the cause of this solitary squamous papilloma of the lung.

We describe a case of solitary papilloma of the bronchus and provide a review of 38 similar cases reported in Japan. A 70-year-old man complained of cough and sputum. Chest X-rays and CT scans revealed atelectasis of the right middle lobe. On bronchoscopy, a polypoid tumor was found at the orifice of the bronchus of the right middle lobe. The tumor was histologically diagnosed as a squamous papilloma with moderate atypia. Because of elevated tumor markers and the reported high incidence of malignant changes in papillomas, the tumor was endoscopically resected by electrosurgical snare. While this procedure resulted in improvement of atelectasis, the chest CT taken subsequently revealed a mass adjacent to the resected polypoid tumor in the middle lobe bronchus. Percutaneous needle biopsy followed by histopathological examination confirmed the tumor to be a squamous cell carcinoma. Only three cases of malignant changes in papillomas have been previously reported in Japan. Electrosurgical snare, which allows the identification of tissue at the tumor base, should be the treatment of choice rather than YAG laser surgery.

The cause of asthmatic attacks in a middle-aged man was disclosed and the relief of his symptoms achieved at one and the same time when he coughed up a tumour which proved to be a solitary bronchial papilloma. The pedicle of the tumour had ruptured as the result of infarction due to thrombosis in stromal blood vessels. Asthmatic attacks, stromal blood vessel thrombosis, and the coughing up of the tumour are three features which have not been reported in the few published accounts of this exceedingly rare bronchial tumour.

A 72-year-old woman with primary biliary cirrhosis complained of dry cough and wheezing. Chest computed tomography showed a tumor arising from the posterior wall of the trachea. Bronchoscopic examination revealed that the tumor was cauliflower-like, with two small polypoid tumors. They were diagnosed as multiple squamous papillomas. The main tumor was recurrent and removed by repeated microwave coagulation therapy (MCT) through bronchoscopy, whereas the two polypoid tumors were likely to disappear spontaneously. Human papilloma virus (HPV) type 6 DNA was detected in the tumor by polymerase chain reaction (PCR) amplification, suggesting that this virus was the cause of her papillomas.

A 64-year-old woman presented with an intractable cough and purulent sputum, and a chest CT revealed a mass within the left lower lobar bronchial orifice. A flexible bronchoscopy demonstrated a red, glistening, nodular single lesion, obstructing the lumen of the left lower lobe of the bronchus, and biopsy of the specimen showed squamous papilloma. Surgical resection was selected for the definite treatment, and a simple left lower lobectomy was performed. Histopathological examination revealed a 1.2 x 1.0 cm sized bronchial obstructing mass and the diagnosis of squamous papilloma was confirmed with low p53, Ki-67 (less than 5 %) and focal weak positive CEA expression. The patient had an uncomplicated postoperative course and remains asymptomatic 3 months afterwards.
