Abstract
Adult Recurrent Respiratory Papillomatosis (RRP) is a rare disease caused by the human papilloma virus in which papilloma grows from the respiratory epithelium. Patients can suffer from significant respiratory distress secondary to tracheal or bronchial obstruction by papilloma and the mainstay of treatment is bronchoscopic debridement. There are a variety of techniques to resect the endoluminal tumor, including CO2 or YAG laser, argon plasma coagulation, microdebrider and cold forceps. There have been documented cases of healthcare workers contracting HPV after exposure to surgical smoke during ablation of papilloma and measures should be taken to avoid inhalation of the smoke plume. For proximal lesions that are accessible to a microdebrider, this appears to be a safe and effective technique that does not generate heat or surgical smoke. The rate of recurrence of adult-onset respiratory papilloma after initial debulking varies and adjuvant medical therapy including intralesional cidofovir, interferon, or oral indole-3-carbinol has been used to slow recurrence. Malignant transformation of adult-onset RRP to squamous cell carcinoma has been reported to occur in 3-7% of cases. Therefore, ongoing surveillance is needed to monitor for disease progression and malignant transformation. Here we describe three patients whose tracheal disease was managed with an Nd-YAG laser and microdebrider. One patient was treated with adjuvant systemic indole-3 carbinol and another was maintained with serial debridement only. The third patient presented with obstructing squamous cell carcinoma of the trachea and was treated with definitive chemoradiation. She presented with a new left mainstem lesion 6 months later which was diagnosed as RRP. She was started on indole-3 carbinol, but unfortunately it transformed to squamous cell carcinoma 8 months later.
