Inverted papilloma of the nose and paranasal sinuses is a tumor not usually associated with childhood. These five cases from the Massachusetts Eye and Ear Infirmary provide the only series in the literature. The patients ranged in age from 6 to 20 years. One case involved the septum exclusively; the patient experienced a recurrence. The other four cases were of sinus origin. One of these patients also experienced recurrences before definitive surgery. Another presented with a simultaneous squamous cell carcinoma. Evaluation of these cases demonstrates that the same successful, comprehensive surgical management advised for adults is justifiable in this younger age group.
