Epibulbar osseous choristoma occurs rarely and is commonly mistaken for a dermoid or dermolipoma. We report two cases: an 8-year-old boy and a 79-year-old lady with epibulbar osseous choristomas where computed tomography showed an extraocular lesion in the temporal quadrant and diagnosis was confirmed by excision biopsy. The osseous component was adherent to the sclera in the young patient, while it was loosely attached to the surrounding tissue in the older patient. We believe that the 79-year-old lady is the oldest reported patient with an epibulbar osseous choristoma.
眼球表面骨化性迷离瘤罕见,常被误诊为皮样囊肿或皮样脂肪瘤。我们报告两例:一名8岁男孩和一名79岁女性患有眼球表面骨化性迷离瘤,计算机断层扫描显示颞侧象限有眼外病变,经切除活检确诊。年轻患者的骨成分与巩膜粘连,而老年患者的骨成分与周围组织疏松相连。我们认为,这位79岁的女性是报道中年龄最大的眼球表面骨化性迷离瘤患者。
