How is Recurrent Respiratory Papillomatosis diagnosed?

Recurrent Respiratory Papillomatosis (RRP) is primarily diagnosed through clinical visualization of papillomas in the airway via laryngoscopy or bronchoscopy, confirmed by a surgical biopsy. Because symptoms often mimic common respiratory issues like asthma or chronic hoarseness, reaching a definitive diagnosis can take several months or even years.

How is Recurrent Respiratory Papillomatosis diagnosed?

The diagnostic process for Recurrent Respiratory Papillomatosis typically begins when a patient presents with persistent hoarseness, stridor, or difficulty breathing. Because these symptoms are non-specific, the "diagnostic odyssey" is common, with many patients initially misdiagnosed with asthma or vocal cord nodules. A definitive diagnosis of Recurrent Respiratory Papillomatosis requires a direct examination of the airway performed by an otolaryngologist (ENT). During this procedure, the physician uses a scope to visualize the wart-like growths and removes a sample of the tissue for histopathological analysis.

What tests confirm the presence of RRP?

While imaging like CT scans may be used to assess the extent of airway involvement, they cannot confirm the diagnosis. The following steps are standard for confirming Recurrent Respiratory Papillomatosis:

• Direct Laryngoscopy/Bronchoscopy: The gold standard for visualizing the papillomatous lesions.


• Biopsy and Histopathology: Microscopic examination of the tissue is essential to confirm the diagnosis and rule out malignancy.


• HPV Typing: Laboratory tests may identify the HPV subtypes (most commonly HPV-6 and HPV-11) associated with Recurrent Respiratory Papillomatosis.

Which specialists should I see?

If you suspect you have Recurrent Respiratory Papillomatosis, it is vital to consult a laryngologist or a pediatric otolaryngologist, as these specialists have the specific expertise to distinguish RRP from other conditions like laryngeal carcinoma or chronic laryngitis. At DiseaseMaps.org, 156 community members have shared their experiences, many noting that seeking care at a specialized tertiary center was the turning point in their diagnostic journey.

Next steps

• Request a referral to a fellowship-trained laryngologist.


• Document your symptoms, including the duration of hoarseness and any breathing difficulties.


• Join the Recurrent Respiratory Papillomatosis community at DiseaseMaps.org to connect with others who have navigated the diagnostic process.


• Ask your provider about participating in clinical trials or registries for rare airway diseases.
