Diagnosis and management of cervical teratomas.

We present three cases of cervical teratoma, two of which were detected prenatally by ultrasound. The two cases diagnosed prenatally showed rapid early growth, which indicated the aggressive nature of the tumour and assisted the parents' decision to terminate the pregnancy. The third case was undiagnosed prenatally and the child was born after a normal pregnancy and uncomplicated vaginal delivery. She recovered well after excision of the teratoma.
