We present the case of a 3-year-old male child with an epibulbar bone choristoma. The patient presented with a hard consistency subconjunctival mass of 8×10mm in the superior-temporal quadrant of his right eye along with vascularisation and a long cilium of approximately 8 to 10mm that touched the corneal surface. The histopathology study showed the presence of trabeculae of mature, compact bone surrounded by fibrous tissue, as well as Havers channels with concentric rings of laminar bone without bone marrow, and with normal osteocytes which defined the diagnosis of epibulbar bone choristoma. Osseous choristoma is the rarest type of the ocular choristoma and should be considered as a differential diagnosis among paediatric epibulbar tumours.
我们报告了一例 3 岁男性患儿患有眶骨骨错构瘤。患者右眼颞上方的球结膜下有一个 8×10mm 的硬性小结节，伴有血管化和大约 8 到 10mm 的长睫毛，触及角膜表面。组织病理学研究显示，存在成熟、致密骨的小梁，周围有纤维组织，以及哈氏管，其具有同心层状骨的环形，没有骨髓，并且有正常的骨细胞，这明确了眶骨骨错构瘤的诊断。骨错构瘤是最罕见的眼部错构瘤类型，应在小儿眶部肿瘤的鉴别诊断中考虑。
