Pathology of laryngeal papilloma

Outline

Laryngeal papilloma is a benign papilloma of the larynx, caused by overproduction of papillae under the epithelial layer.

Causes: unclear, viral, endocrine ...

The disease can be found in the ages: children, adults, the elderly.

Disease often recurs.

Symptom

Mechanical symptoms

Mild, moderate, severe, loss of voice, and hoarseness gradually increase with the size of the tumor.

Inflammation of superinfection: dyspnea is common in children due to a narrow growth of the glottis.

Physical symptoms

Laryngoscopy:

In adults: a lump may be found on the surface of the vocal cord, usually on the upper surface and free margin of the vocal cord.

In children: direct laryngoscopy reveals a pink or dark strawberry-like mass, scattered on the vocal cords, laryngeal, vocal cord, funnel cartilage. Sometimes the tumor has spread to the vestibular larynx spread to the trachea.

Diagnose

Diagnosis is confirmed thanks to biopsy.

Differential diagnosis: with tuberculosis, syphilis, cancer, chronic laryngitis. Need to test Mantoux, sputum test, chest X-ray, BW reaction test, biopsy.

Treatment

Drug treatment with little results.

Surgical treatment of papillectomy with pliers, microsurgery, tumor removal with CO2 laser.

Prognosis

Easy to relapse due to not removing all of the tumor.

Children who reach puberty usually go away on their own.

Adults can develop cancer.

Do not use radiation therapy to treat papilloma because they are ineffective and easily cause cancer.
