Abstract：
Sinonasal inverted papilloma (SNIP) is one of the most common benign epithelial tumors but rarely occurs in children. The case of a 9-year-old Chinese boy, who presented with a left maxillofacial hump, nasal obstruction, and left nasal cavity and maxillary sinus masses under nasal endoscopy, is reported. The lesion was first diagnosed as a sinonasal tumor. However, to our surprise, the mass was determined to be an inverted papilloma after a detailed histological examination. We retrospectively reported the clinical data of this case and reviewed the relevant literatures on SNIP. This report aims to provide new insights into the clinical characteristics in children with SNIP and improve the understanding of this disease.

鼻窦内翻性乳头状瘤（SNIP）是最常见的良性上皮性肿瘤之一，但很少发生在儿童中。一个9岁的中国男孩的案件，出现左颌面驼峰的人，鼻塞,鼻内镜下左侧鼻腔和上颌窦肿块，据报道。该病变最初被诊断为鼻窦肿瘤。然而,令我们惊讶的是，经过详细的组织学检查，确定肿块为内翻性乳头状瘤。我们回顾性报道了该病例的临床资料并复习了有关SNIP的相关文献。本报告旨在为SNIP患儿的临床特征提供新的见解，并提高对该病的认识。
