Laryngeal papillomatosis



Other Names:
Warts in the throat; Juvenile laryngeal papillomatosis (subtype); Recurrent laryngeal papillomatosis (subtype)

Laryngeal papillomatosis is a form of recurrent respiratory papillomatosis where tumors (papillomas) grow in the larynx (voice box).[1] Symptoms usually begin with hoarseness and/or a change in the voice. Some people may experience difficulty breathing (dyspnea) and/or experience other life-threatening complications if the papillomas block the airway.[2] The tumors may vary in size and grow very quickly. They often grow back even when removed. Laryngeal papillomatosis  is caused by two types of human papilloma virus (HPV), called HPV 6 and HPV 11.[1]

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Clinical Research Resources

  • ClinicalTrials.gov lists trials that are related to Laryngeal papillomatosis. Click on the link to go to ClinicalTrials.gov to read descriptions of these studies.

    Please note: Studies listed on the ClinicalTrials.gov website are listed for informational purposes only; being listed does not reflect an endorsement by GARD or the NIH. We strongly recommend that you talk with a trusted healthcare provider before choosing to participate in any clinical study.

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.

In-Depth Information

  • The Monarch Initiative brings together data about this condition from humans and other species to help physicians and biomedical researchers. Monarch’s tools are designed to make it easier to compare the signs and symptoms (phenotypes) of different diseases and discover common features. This initiative is a collaboration between several academic institutions across the world and is funded by the National Institutes of Health. Visit the website to explore the biology of this condition.
