A rare case: Endobronchial solitary mixed papilloma

Endobronchial solitary papillomas are extremely rare lung neoplasms origi-nating from the bronchial surface epithelium. They often present with cough or recurrent hemoptysis. These tumors are benign, but they should be fol-lowed closely because they may even have a low probability of malignant transformation features. It should be kept in mind that malignancy may devel-op especially if the patient is a smoker. Although the etiology is not known for certain, it is thought to be caused by human papillomavirus in some cases. A 43-year-old male patient was admitted with a complaint of chronic cough. Rigid bronchoscopy was performed for diagnostic and therapeutic purposes after imaging techniques revealed a lesion obstructing the lumen of the right main bronchus. The pathology result was reported as mixed bronchial papil-loma. We aimed to present our case because of its rarity and to indicate that chronic cough must be further evaluated.
