A laryngoscopic view of a classical case of RDD with laryngeal involvement. (a) This picture shows that the nodular lesions with smooth surfaces were mainly present in the right vocal cord and the posterior region of the subglottic area. (b) This picture shows that the nodular lesions with smooth surfaces were mainly present in the right vocal cord and the anterior region of the subglottic area. (c) This picture shows that the nodular, ulcer-free lesions with smooth surfaces were mainly present in the right vocal cord and entire subglottic area. (d) This picture shows the nasopharyngeal manifestation of the same patient in panel (c).
