摘　　要：BACKGROUND Choristoma is a rare,benign,congenital proliferative tumor,with osseous choristoma being the rarest.Although the tumor is benign,effective identification is needed for its diagnosis and treatment.Here,we report the diagnosis and successful surgical treatment of two patients with osseous choristoma.CASE SUMMARY Two patients,a young female and young male patient,were found to have a mass on the ocular surface.The tumor presented on the superior temporal bulbar conjunctiva in the first patient and on the upper eyelid in the second patient.Ultrasound biomicroscopy detected a strong echo with clear boundaries covering the lower echo,and computed tomography examination revealed calcification.Both patients underwent surgery,and histopathological evaluation of the mass showed osseous choristoma.They were treated by excision and subsequently cured.CONCLUSION Osseous choristomas are usually asymptomatic.Our patients were cured immediately after surgery,suggesting that surgical treatment is an effective strategy.
