Juvenile laryngeal papillomatosis. An epidemiological study from the Copenhagen region
1University ENT Department, Gentofte Hospital, Hellerup, Denmark.
Insights
Juvenile laryngeal papillomatosis (JLP) is rare in children, with most cases having a good prognosis. However, some JLP cases persist into adulthood, indicating a need for long-term monitoring.
Area of Science:
- Pediatric Otolaryngology
- Epidemiology
- Respiratory Medicine
Background:
- Juvenile laryngeal papillomatosis (JLP) is a rare condition affecting the larynx in children.
- Understanding the epidemiology and long-term outcomes of JLP is crucial for patient management.
Purpose of the Study:
- To determine the incidence and prevalence of JLP in the Copenhagen region.
- To evaluate the long-term prognosis and potential for recurrence of JLP.
Main Methods:
- Epidemiological study identifying all patients treated for JLP over a 4-year period.
- Analysis of incidence, prevalence, and clinical course, including long-term follow-up data.
Main Results:
- The incidence of JLP was 0.6/100,000 and prevalence was 0.8/100,000 in children aged 0-14 years.
- Most JLP cases demonstrated a good prognosis with short duration and low morbidity.
- A significant minority of patients experienced long-lasting disease, with 7 of 12 adult patients having a median quiescent period of 21 years.
- Spread of papillomas to the bronchogenic system was identified as a serious prognostic indicator.
Conclusions:
- JLP generally has a favorable prognosis in most pediatric cases.
- Regression during childhood does not guarantee complete recovery, as evidenced by late recurrences.
- Bronchogenic spread of papillomas indicates a poorer prognosis, necessitating vigilant monitoring.
Abstract:
All 23 patients treated for juvenile laryngeal papillomatosis (JLP) in the Copenhagen region during a 4-year-period were identified for this epidemiological study. The incidence of JLP was 0.6/100,000 among the population at risk, children aged 0-14 years, and the prevalence was 0.8/100,000. It is concluded that the condition in most cases has a good prognosis, i.e., short duration and low morbidity. Only in a few cases JLP will take a long-lasting course. Regression before or during puberty does not in all cases ensure complete recovery. Thus, 7 of 12 adult patients experienced a quiescent period of 21 years (median). Spread of papillomas to the bronchogenic system seems to be a serious prognostic sign.
