According to Gonzalez-Crussi System, sacrococcygeal teratoma is graded on a scale from 0 - 3, based on the histology:^[1]


Grade	Microscopic Features

Grade 0	Tumor contains only mature tissue.
Grade I	Tumor contains rare foci of immature tissue. Less than 10% tissue is immature
Grade II	Tumor contains moderate quantities of immature tissue. Upto 10 - 50% tissue is immature
Grade III	Tumor contains large quantities of immature tissue with or without malignant yolk sac elements. More than 50% tissue is immature
