Abstract
INTRODUCTION: (Chondrometaplasia of the larynx is a rare disease. We report a case that presented at the otolaryngology department in our institute in 2015.) PRESENTATION OF CASE: A 62year old man without any history of trauma presented with progressive dysphonia, dyspnoea, without any dysphagia. A fibreoptic laryngoscopic examination revealed nodular mass arising at the junction of anterior 1/3rd and posterior 2/3rd of left vocal cord.
DISCUSSION: A computed tomography scan of the neck region showed a rounded and circumscribed mass without infiltration of the surrounding tissues. Histological investigation of the lesion revealed the presence of fibroelastic cartilaginous tissue, surrounded by a thin rim of fibrous tissue, with rare hypercellular areas, occasional binucleated cells, slight hyperchromasia, and an irregular nuclear profile. Mitotic activity was absent.
CONCLUSION: The patient didn't have history of laryngeal trauma. Subacute and progressive onset of clinical symptoms and histological and radiological findings helps to distinguish the chondrometaplastic nature from true laryngeal cartilaginous tumours, such as chondroma and low grade chondrosarcoma.
