Ameloblastoma is a rare, benign (99%) or malignant (1%) tumour, which has derived from dental mesenchyme. We present a case of a patient mainly complaining about obstruction on the right nasal cavity. Endoscopy and computed tomography revealed a soft tissue mass occupying the maxillary sinus to the middle meatus causing complete obstruction of the right nasal cavity. Endoscopic en block removal of the lesion and biopsy confirmed follicular ameloblastoma. Literature review confirms the extremely rare frequency of ameloblastoma. The aim of the present study is to expand on our knowledge of a rare pathological entity that can frequently be misdiagnosed.
成釉细胞瘤是一种罕见的肿瘤，99%为良性，1%为恶性，起源于牙间充质。我们报告一例主要以右侧鼻腔阻塞为主诉的患者。内镜检查和计算机断层扫描显示一个软组织肿块占据上颌窦至中鼻道，导致右侧鼻腔完全阻塞。通过内镜整块切除病变并活检确诊为滤泡型成釉细胞瘤。文献综述证实成釉细胞瘤极为罕见。本研究的目的是拓展我们对这种常被误诊的罕见病理实体的认识。
