Laryngeal Papillomatosis
Overview
Plain-Language Overview
Laryngeal Papillomatosis is a condition where small, wart-like growths develop in the voice box or larynx. These growths are caused by an infection with the human papillomavirus (HPV), which affects the cells lining the airway. The main body system involved is the respiratory system, specifically the larynx, which is important for breathing and speaking. These growths can cause symptoms like a hoarse voice, difficulty breathing, or a chronic cough. The condition can affect both children and adults and may require repeated medical procedures to remove the growths. It is not cancerous but can cause significant problems with voice and airway obstruction if untreated.
Clinical Definition
Laryngeal Papillomatosis is a benign neoplastic disorder characterized by the proliferation of exophytic squamous papillomas within the larynx, caused primarily by infection with HPV types 6 and 11. The disease manifests as multiple wart-like lesions on the vocal cords and other laryngeal structures, leading to voice changes and potential airway obstruction. It is the most common benign tumor of the larynx in children and can present as either juvenile-onset or adult-onset forms. The pathogenesis involves viral-induced epithelial hyperplasia with a tendency for recurrence due to viral persistence. Although benign, the lesions can cause significant morbidity due to repeated growth and airway compromise. Malignant transformation is rare but possible, especially with co-infection by high-risk HPV types or in immunocompromised patients.
