Thoracic computerized tomography scans revealed bronchiectasis of the right upper lobe, mediastinal lymphadenopathy and bilateral emphysematous areas in the lung field. On bronchoscopy, a polypoid hemorrhagic lesion was seen at the orifice of the bronchus of the right upper lobe, a biopsy specimen was obtained and diagnosis was made of squamous papilloma with a malignant potential.The final histopathologic diagnosis was squamous papilloma and carcinoma in situ. In conclusion, a solitary squamous papilloma may present with bronchiectasis and hemoptysis and may show malignant degeneration with carcinoma in situ.
