Epibulbar osseous choristoma

Osseous choristoma constitutes the rarest category of choristoma affecting pediatric ocular regions. It predominantly composed of ectopically ossified tissue, which can involve anywhere in the eye and typically manifest as isolated anomalies. This study presents the case of an 8-year-old male patient diagnosed with epibulbar osseous choristoma. The choristoma exhibited significant adhesion to the superficial sclera, as corroborated by comprehensive diagnostic imaging, encompassing both macroscopic and pathological analyses. This case contributes to a deeper understanding of the lesion's primary localization, pathological features, and etiological mechanisms, thereby informing differential diagnosis and surgical treatment approaches.
