甲状軟骨両翼に生じた喉頭軟骨腫例

抄録

An 80-year-old male patient with multiple laryngeal chondromas is reported. Bilateral thyroid cartilage masses were identified incidentally on CT. The masses remained constant in size over a two-year follow-up period, however, pharyngolaryngeal endoscopy at the end of two years showed submucosal swelling of the false folds of the larynx. A mass lesion measuring 15 mm in diameter in the right lamina of the thyroid cartilage was surgically resected by the cervical approach under local anesthesia. Histopathological examination showed mild proliferation of chondrocytes without nuclear atypia in a hyaline cartilage matrix, based on which the diagnosis of laryngeal chondroma was made. Another mass measuring 7 mm in diameter found in the left lamina of the thyroid cartilage was left unresected and will be followed up.
