Elastic Cartilaginous Metaplasia of Vocal Cord Nodules

" RESULTS The average age of patients with cartilaginous changes of the vocal cords was 52 years; 19 lesions occurred in males ranging in age from 31 to 70 years; 15 lesions occurred in females, ranging in age from 27 to 70 years ( Fig. 1). tilaginous changes. All cartilaginous nodules were located on the true vocal cords and none was contiguous with other cartilaginous structures of the larynx. Elastic cartilage nodules of the vocal cords have been termed "chondromas" of the vocal cords and grouped with cartilaginous tumors of the larynx. In a review of 377 vocal cord nodules resected at the Massachusetts Eye and Ear Infirmary over a two-year period, 34 nodules were found to contain elastic cartilage. A striking feature was the gradation present from elastic tissue with cartilaginous change to circumscribed mature cartilage "tumors", suggesting a metaplastic change rather than a neoplasm.
