We report the case of a 25-year-old man who had a penetrating keratoplasty for keratoconus. A year and a half after surgery a cyst was noted in the anterior chamber, which was observed to enlarge over six months. Because of anxiety about endothelial touch, it was removed surgically. Histologically the cyst was composed of stratified, non-keratinized squamous epithelium attached to loose fibrovascular tissue including islands of melanin-containing epithelial cells. This was interpreted as an epithelial implantation cyst of the anterior chamber of corneal origin attached to iris tissue.

我们报告一例25岁男性圆锥角膜患者行穿透性角膜移植术的病例。术后一年半，前房内发现一个囊肿，观察发现其在六个月内逐渐增大。由于担心内皮接触，遂通过手术将其切除。组织学检查显示，囊肿由附着于疏松纤维血管组织的分层、非角化鳞状上皮组成，其中包括含黑色素上皮细胞岛。这被解释为起源于角膜的前房上皮植入性囊肿并附着于虹膜组织。
