A 16-year-old boy complains of difficulty in breathing through his nose. Endoscopy reveals a tumor infiltrating the nasopharynx. Histology reports this as a juvenile nasopharyngeal haemangiofibroma. The boy's anxious mother requests information concerning the lesion. What should she be told?
It is a premalignant lesion. It usually occurs with laryngeal obstruction. It is treated with radiotherapy. It may proceed to destroy surrounding bone.
