Inverted Schneiderian Papilloma of the Sinonasal Tract in Children

Abstract

Inverted schneiderian papilloma of the sinonasal tract is an uncommon lesion in adults and is even less common in children. Nine cases occurring in the pediatric age group have been reported in the literature. We describe two more childhood cases of inverted schneiderian papilloma, one occurring in a 15-year-old girl and the other in a 10-year-old boy. This lesion in children behaves similarly to that in adults. When treated by intranasal surgery, it usually recurs. With this report we would like to illustrate the diagnostic and differential diagnostic elements of this lesion and increase the awareness of this entity in the pediatric age group.
