Diagnostic Considerations

Due to its nonspecific clinical manifestations, recurrent respiratory papillomatosis (RRP) is easily mistaken for asthma, acute laryngitis, upper respiratory infection, or bronchitis. [18]

Other conditions to consider in the diagnosis of RRP include the following:

  • Benign lung, laryngeal, or tracheal tumors

  • Laryngeal infection

  • Malignant laryngeal or tracheal tumors

  • Squamous cell lung cancer
