BACKGROUND
A primary conjunctival epithelial cyst is an uncommon lesion that consists of nonkeratized, stratified squamous epithelium without dermal appendages.
METHODS
Case report.
RESULTS
A 57-year-old woman presented with a soft mass in the anterior portion of the nasal orbit. Magnetic resonance imaging demonstrated a rounded, cystic lesion between the right eye and the nasal bone. Histopathological examination following complete surgical excision disclosed a conjunctival epithelial cyst lined by nonkeratinized cuboidal epithelium without goblet cells and adnexal structures.
CONCLUSION
A conjunctival epithelial cyst should be considered in the differential diagnosis of a mass in the anterior portion of nasal or superonasal orbit.
背景
原发性结膜上皮囊肿是一种罕见病变，由无皮肤附属器的非角化复层鳞状上皮构成。
方法
病例报告。
结果
一名57岁女性患者，鼻侧眶前部出现一软性肿物。磁共振成像显示右眼与鼻骨之间有一圆形囊性病变。完整手术切除后进行组织病理学检查，发现一个由无杯状细胞和附属结构的非角化立方上皮衬里的结膜上皮囊肿。
结论
在鼻侧或鼻上方眶前部肿物的鉴别诊断中应考虑结膜上皮囊肿。
