Overview
Sacrococcygeal teratoma (SCT) is classified into 4 different categories according to American Academy of Pediatrics Surgery classification.[1][2]
Classification
American Academy of Pediatrics Surgery Section System classifies Sacrococcygeal teratoma depending on the anatomical location of the tumor.
- Type I - extensively exterior with minimal pelvic involvement.[1][2]
- Type II - has pelvic involvement giving tumorous growth an "hour-glass" appearance.
- Type III - has more pelvic and intra-abdominal involvement than external.
- Type IV - extensive pre-sacral involvement without external growth.
Staging of Sacrococcygeal Teratoma
- I - Complete resection; negative tumor margins[3]
- II - Microscopic residuals; lymph node negative
- III - Lymph node involvement; Gross residual on biopsy; retroperitoneal node may be positive or negative
- IV - Distant metastasis may involve liver
Grade
According to Gonzalez-Crussi System, Sacrococcygeal teratoma is graded on a scale from 0-3, based on the histology:[2]
- Grade 0-Tumour contains only mature tissue.
- Grade 1-Tumour contains rare foci of immature tissues.
- Grade 2-Tumour contains moderate quantities of immature tissues.
- Grade 3-Tumour contains large quantities of immature tissue with or without malignant yolk sac elements.
