How long can vocal cord leukoplakia worsen?

summary

Vocal cord leukoplakia refers to the white plaque like protrusion on the surface of vocal cord mammary membrane, which is caused by abnormal growth or maturation of vocal cord mammary membrane epithelium and hyperkeratosis. So let's share how long will vocal leukoplakia worsen?.

How long can vocal cord leukoplakia worsen?

First, the common pathological classification of laryngeal epithelial precancerous lesions is the 2005 WHO classification of dysplasia: squamous epithelial simple hyperplasia, atypical hyperplasia (mild, moderate, severe) and carcinoma in situ. Vocal cord leukoplakia has a certain tendency of malignant transformation, which is often called laryngeal precancerous lesions, The degree of dysplasia may be a risk factor for recurrence and canceration of vocal cord leukoplakia.

Second, although some chronic laryngeal lesions are benign, they are prone to canceration under certain factors, which are called "precancerous lesions", including vocal cord leukoplakia and laryngeal papilloma.

Third, in the former, white plaques formed by epithelial hyperplasia and keratinizing accumulation could be seen on the vocal cords; The latter grows papillary new organisms in the larynx, which is also found in children. It is easy to relapse after surgery, and the middle-aged and elderly patients are prone to malignant transformation. Laryngeal papilloma is a kind of tumor between benign and malignant. It should be followed up regularly and closely. If necessary, the local tissue should be taken for pathological examination, especially when the cell growth is active and atypical hyperplasia appears in the pathological report.

matters needing attention

Vocal cord leukoplakia, as a precancerous lesion of laryngeal carcinoma, has a certain tendency of malignant transformation, and laryngeal carcinoma and leukoplakia often relapse after operation. Therefore, in-depth study of the cause of vocal cord leukoplakia, early prevention and treatment of the cause of vocal cord leukoplakia and laryngeal cancer is extremely important, and can also provide the basis for the prevention of recurrence and malignant transformation.
