A huge immature cervical teratoma in a newborn: report of a case.
A neonate with a large cervical mass was transferred to our hospital at 4 days of age. A computed tomography scan showed a contrast-enhanced solid mass with multiple cystic elements and fine calcification. Ultrasonography also revealed a predominantly solid mass with calcification, containing multiple cysts. These studies suggested a teratoma, but could not rule out a hemangioma. The tumor was removed on the 12th day of life. A pathological study revealed an immature teratoma that demonstrated fetal type cartilage and an immature neural tube. The operative complete removal of a cervical teratoma in neonates is recommended as soon as possible. The management of a pediatric cervical teratoma should also be similar to that of a sacrococcygeal teratoma. The incidence of cervical teratoma in all pediatric teratomas ranges from 2.3%-9.3% in the West, and from 1.6%-8.3% in Japan.
