A sixty-four year old male patient came to the emergency service with a haemoptysis complaint for which his postero-anterior chest X-Ray and computerized thorax tomography had no pathological findings. To find the origin of the haemoptysis, indirect laryngoscopy and endoscopy inspections were made. However, there was no pathology found on these inspections. At fiberoptic bronchoscopy a lobulated, white lesion approximately 0.5 cm in diameter was found at the entrance of left lower lobe anterior segment. The lesion was removed by forceps biopsy resection. The pathological inspection of this lesion resulted in a diagnosis of endobronchial papilloma. Examination of this biopsy with HPV DNA gave negative result. To plan his treatment, we examined the patient 2 weeks and 6 months later. He had no complaint and his bronchoscopic inspection had no pathological findings. We decided to examine him periodically. The endobronchial solitary papilloma is a rare benign tumor of the bronchus but we must be careful about smokers since this benign lesion may become malignanat. (Tur Toraks Der 2011; 12: 165-7)
