Orbital tooth - not always a teratoma : a case report

ABSTRACT

A 7-year-old girl presented with a painless firm to cystic mass in the infero-temporal quadrant of her right orbit since birth. The mass had recurred with a cutaneous sinus after initial surgery. Right eye vision was affected by mass induced astigmatism. The anterior and posterior segments were normal. Magnetic Resonance Imaging of the orbit suggested a mature teratoma within the orbital bone. Mass excision showed a fully developed molar tooth within a cyst associated with a cutaneous sinus. Histopathological examination reported odontogenic choriostoma. We report this unique case of orbital odontogenic choristoma in an unusual location, associated with a cutaneous sinus, emphasizing the need for complete excision to prevent recurrence.
