Classification

• Teratomas are classifiable based on different general characteristics and site of origin.
  • Sacrococcygeal teratoma
  • Mediastinal teratoma
  • Ovarian teratoma

• Historically teratomas were classified as:
  • mature
  • immature
• In adults teratomas likely demonstrate malignant inclination and behavior. In Children, different tumors from various origins are reported, while predominantly we may see sacrococcygeal tumors.
• We can also classify teratomas to benign and malignant tumors. The malignant types are named teratocarcinomas.
