23-year-old Nagabhushanam Siva had a bulging tumor near her left eye.

Dr K Vasantha, the director of the government hospital in Chennai said that the growing tumor had damaged the optic nerve and had left the young women without eyesight. “A teratoma is a mass of tissue that contains cysts and sometimes contains hard tissues but fully grown teeth is so very rare," she added.
Teratomas around the orbital region of the eye are very rare and only 70 such cases have been reported globally.
