sacrococcygeal teratoma

Sunday 18 July 2004

Sacrococcygeal teratoma (SCT) is the most common tumor of the newborn with an incidence of 1 in 35,000 to 40,000 live births.

In the newborn, the sacrococcygeal site is located at the base of the tailbone (coccyx), is the most common location of teratomas in newborns.
