Peribulbar osseous choristoma is a benign, solid nodule; it is a subtype of epibulbar choristomas (belongs to single tissue choristomas), consisting of pure bony tissues. Epibulbar osseous choristoma is the rarest subtype of epibulbar choristomas, with only 65 cases reported since the mid-19th century; so, the rarity of the disease drove me to report it. A 7-year-old female presented with a painless left ocular superotemporal mass, which was present since birth and located under the conjunctiva. The primary diagnoses included lipodermoid and subconjunctival foreign bodies. Ocular interventions included a B-scan, examination under anesthesia and surgical excision of the mass in toto, and the histopathological examination showed that it was an osseous choristoma.
球周骨化性迷离瘤是一种良性实性结节；它是球表迷离瘤的一种亚型（属于单一组织迷离瘤），由纯骨组织构成。球表骨化性迷离瘤是球表迷离瘤中最罕见的亚型，自19世纪中叶以来仅有65例报道；因此，该病的罕见性促使我对其进行报道。一名7岁女性因左眼颞上方无痛性肿物就诊，该肿物自出生即存在，位于结膜下。初步诊断包括皮样脂肪瘤和结膜下异物。眼部干预措施包括B超检查、麻醉下检查及肿物完整切除，组织病理学检查显示为骨化性迷离瘤。
