Laryngeal location is the most frequent. The bronchial involvement remains unusual. It represents 0.38% of pulmo- nary tumors. We report the case of a 39-year-old, smoker man, who con- sulted for a cough following during six months with persistent radiological opacity despite antibiotic treatment. The physical examination was without particularities. Flexible bronchoscopy revealed a swollen endobronchial lesion completely obstructing the orifice of the intermediate trunk. Bronchial biop- sies at this level showed inflammatory mucosa. The chest CT scan objectified an endobronchial tissular mass in the intermediate trunk. Pulmonary neopla- sia was suspected. Diagnostic and therapeutic surgery was performed. Histo- pathological examination concluded to an endobronchial squamous papil- loma. Keywords Papilloma, Smoking, Lung, Cancer, Surgery 1. Introduction The papilloma is a rare benign entity [1]. The Solitary respiratory papilloma (SRP) is an uncommon pathologic condition of the lower respiratory tract, with less than 60 cases reported in the literature [2]. It accounts for 0.38% of all pul- monary tumors. Although the precise etiology of respiratory papillomas remains How to cite this paper: Hanen, S., Ikbel, K., Fethi, D.M., Mahdi, A., Monia, A., Aida, A.-K. and Lamine, M.M.
