角膜囊肿Cornea Cyst · 眼 · 特殊感觉系统 · NTP ntp-0345
诊断要点：角膜上皮包涵囊肿应诊断为“眼，角膜 - 囊肿”。该病变应诊断为存在，但不进行严重程度分级。
病变描述
角膜上皮包涵囊肿（Corneal epithelial inclusion cysts）（Figure 1、Figure 2）由基质内空腔构成，空腔衬覆单层扁平细胞，腔内充满漩涡状角蛋白样物质。囊肿周围邻近基质内可继发肉芽肿性炎症。角膜包涵囊肿可起源于胎儿期，也可在出生后因物理性创伤或溃疡导致角膜上皮细胞移位并陷入基质内而发生。
诊断与分级建议（NTP 共识）
角膜上皮包涵囊肿应诊断为“眼，角膜 - 囊肿”。该病变应诊断为存在，但不进行严重程度分级。任何继发性炎症不应单独诊断（除非其严重程度足以需要单独诊断），但应在病理学描述中予以描述。

Comment：
Corneal epithelial inclusion cysts ( Figure 1 and Figure 2 ) consist of a stromal cavitation lined by a single layer of flattened cells and filled with whorls of keratin-like material. There may be secondary granulomatous inflammation in the adjacent stroma surrounding the cyst. Corneal inclusion cysts may arise during the fetal period or may arise postnatally when corneal epithelial cells become displaced and entrapped in the stroma because of physical trauma or ulceration.
Recommendation：
Corneal epithelial inclusion cysts should be diagnosed as "eye, cornea - cyst." This finding should be diagnosed as present without assignment of a severity grade. Any secondary inflammation should not be diagnosed separately (unless warranted by severity), though it should be described in the pathology narrative.
