Laryngeal keratosis

Introduction to larynx keratosis Laryngeal keratosis is a laryngeal mucosal epithelial lesion characterized by hyperplasia and keratinization of the epithelium. The underlying cause is unclear and may be related to chronic inflammatory irritation or smoking, inhalation of irritating substances, etc. Symptoms are throat discomfort, foreign body sensation is obvious, keratosis causes vocal cords to be incompletely closed and hoarse. There are two clinical types: (1) white spot disease. (2) papillary keratosis. The main symptoms of the patient are throat foreign body sensation, sometimes itching, severe cough can cough up white keratinized material. If the keratin is long in the vocal cords, there may be hoarseness. Laryngoscopy, it can be seen that the laryngeal mucosa grows scattered spiny yellow-white mites, and the keratosis of the pliers is harder. If it is pulled out, the susceptibility of the base is very tight, and there is a bleeding wound after the extraction. Most of them are accompanied by keratinized substances in the throat, oropharynx, especially the ticks of the almonds. basic knowledge The proportion of illness: 0.003% Susceptible people: no specific population Mode of infection: non-infectious Complications: oral cancer

Causes of larynx keratosis

The cause may be related to chronic inflammatory irritation, often accompanied by pharyngeal keratosis.

Local mucosal epithelial keratinization, stacking white small tri-conical or conical protrusions, inflammation of the surrounding mucosa, normal submucosa. May occur in any part of the laryngeal mucosa.

Laryngeal keratosis prevention

The treatment does not advocate cryotherapy, and the systemic application of retinoic acid should be cautious and pay attention to antifungal infection.

Laryngeal complication Complications, oral cancer

It is a kind of precancerous lesion of oral cancer.

Symptoms of laryngokeratosis common symptoms throat itching throat itching cough throat sensation hoarseness

The main symptoms of the patient are throat foreign body sensation, sometimes itching, severe cough can cough up white keratinized material. If the keratin is long in the vocal cords, there may be hoarseness. Laryngoscopy, it can be seen that the laryngeal mucosa grows scattered spiny yellow-white mites, and the keratosis of the pliers is harder. If it is pulled out, the susceptibility of the base is very tight, and there is a bleeding wound after the extraction. Most of them are accompanied by keratinized substances in the throat, oropharynx, especially the ticks of the almonds.

Laryngeal leukoplakia can occur in any part of the larynx, but it is more common in vocal cords and ventricular bands. Laryngoscopy is characterized by plaques or patches, usually single, about a few millimeters in size. Light, white spots are soft, the boundaries are clear, slightly above the mucosal surface. The heavy one is scorpion or granular. If accompanied by erosion, it should be considered that there may be malignant changes.

Examination of larynx keratosis

Laryngoscopy revealed chronic congestion of the laryngeal mucosa, with a white point-like conical protrusion on the surface, and a blood-filled area around it, which can be detached but easily regenerated.

Pathological examination: epithelial hyperkeratosis, cell atypical hyperplasia and epithelial abnormal proliferation.

Diagnosis and differentiation of larynx keratosis

diagnosis

Patients with clinically diagnosed leukoplakia should be promptly biopsied. Those with epithelial atypical hyperplasia should be closely followed up.

Differential diagnosis

It is differentiated from laryngeal foreign body and laryngeal sore.
