dc.description.abstract 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 × 10 mm in the superior-temporal quadrant of his right eye along with vascularisation and a long cilium of approximately 8 to 10 mm 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. en_US

El paciente presentaba una masa subconjuntival de consistencia dura de 8 × 10 mm en el cuadrante superotemporal del ojo derecho con vascularización y presencia de cilios largos de aproximadamente 8 a 10 mm que tocaban la superficie corneal. El estudio histopatológico evidenció la presencia de trabéculas de hueso compacto maduro rodeado de tejido fibroso, canales de Havers con anillos concéntricos de hueso laminar sin médula ósea y con osteocitos normales, lo cual definió el diagnóstico de coristoma óseo epibulbar. El coristoma óseo es el tipo más raro de coristomas oculares y debe considerar en el diagnóstico diferencial de los tumores epibulbares pediátricos. es_PE
