Abstract:
Laryngeal neoplasm is the second most common malignancy of the upper aerodigestive tract. About 85% to 95% of laryngeal malignancies are squamous cell carcinoma that arises from the epithelial lining of the larynx. The exact cause of laryngeal neoplasm is unknown, but certain risk factors can affect the chances of developing it. Chronic inflammation is a mutagen factor confirmed in the carcinogenesis of various tumor. Inhalation injuries cause histopathologic damage to laryngeal mucosa and inflammation change. This long term inflammation may leads to the development of dysplasia and malignant transformation. Recently, we experienced a case of malignant transformation of laryngeal mucosa after inhalation injury patient 25 years ago. Herein, we reported this rare case and review the relevant literature.
