Sumario:BACKGROUND: Pleomorphic adenomas occurring in the adult nasopharynx are rare, with our literature search identifying only 11 previous English-language reports. We document the unusual case of a large nasopharyngeal pleomorphic adenoma that was resected using radiofrequency coblation via an endoscopic transnasal approach. METHODS: A 39-year-old male presented with worsening nasal congestion, intermittent otalgia, and a progressive change in voice. Flexible nasendoscopy showed a large homogeneous mass occupying the postnasal space, and computed tomography confirmed a 28 × 31 × 22 mm nasopharyngeal tumour. The biopsy-proven benign tumour was locally dissected using a coblator-assisted transnasal approach. RESULTS: Histology confirmed complete excision of a myoepithelial-rich pleomorphic adenoma. The patient was symptom-free postoperatively, and no signs of recurrence were seen at one-year follow-up. CONCLUSIONS: This is a useful addition to the existing literature on surgical procedures used to treat benign pathology in the nasopharynx. The minimally invasive technique was well tolerated and had favourable patient outcomes.
