An autopsy case of amniotic band syndrome with bilateral epibulbar choristoma is described. The left eye reveals a complex choristoma and the right eye a dermis-like choristoma. Both choristomatous lesions included lenticular tissue suggesting that rupture of the amnion, which is the initial event of amniotic band syndrome, might have occurred at about the fourth week of gestation. Since the other systemic manifestations of amniotic band syndrome are considered to be compression deformities of the fetus caused by oligohydramnios or amniotic band, the occurrence of epibulbar choristomas in both eyes in this case suggests that a compression mechanism may play a role in the pathogenesis of epibulbar choristoma.
本文描述了一例伴有双侧眼球表面脉络膜瘤的羊膜带综合征尸检病例。左眼可见复杂脉络膜瘤，右眼可见真皮样脉络膜瘤。两个脉络膜瘤病变均包含晶状体组织，提示羊膜带综合征的起始事件——羊膜破裂，可能发生在妊娠约第4周。由于羊膜带综合征的其他全身表现被认为是羊水过少或羊膜带导致的胎儿压迫畸形，该病例双眼出现眼球表面脉络膜瘤提示压迫机制可能在眼球表面脉络膜瘤的发病机制中起作用。
