Benign Cystic Teratoma; A Rare Presentation of a Retroperitoneal Teratoma Compared to a More Convent
Teratomas are among the most common pediatric tumors and are the most common tumors diagnosed prenatally. The vast majority are either sacrococcygeal or head and neck in origin. However, other sites are common and teratomas comprise 40% of all ovarian tumors. Here we report an exceedingly rare case of a large retroperitoneal teratoma diagnosed at the age of 2 and compare it with a more conventional case of an ovarian teratoma diagnosed in an 11 year old who presented with torsion. Both teratomas were surgically excised without complications. Both were pathologically confirmed to be mature cystic teratomas.
