Abstract
Recurrent respiratory papillomatosis (RRP) is a disorder characterized by the frequent recurrence of benign neoplasms in the respiratory tract. Some patients with RRP develop laryngeal papilloma, while others present with extralaryngeal lesions in the nose, pharynx, and trachea. The present study aimed to determine the pharyngeal sites where RRP-related lesions develop more frequently. We retrospectively reviewed the medical records of 127 patients treated at our department between January 2015 and December 2020. We compared the human papilloma virus (HPV) infection status and differences in tumor location between 41 patients with RRP and 86 patients with pharyngeal papilloma (PP). In the RRP group, extralaryngeal papillomata were observed in 10 patients, eight (19.5%) of whom presented with lesions in the inferior wall of the nasopharynx (IWoN). On the contrary, only one patient with PP (1.1%) developed papillomata in this region. IWoN papilloma was significantly more likely to arise in the RRP group than in the PP group (p = 0.0004). In RRP, pharyngeal lesions frequently arise in the IWoN, while this region remains largely unaffected in patients with PP.
