Overview

Sacrococcygeal teratoma is classified into four different categories according to the American academy of pediatrics surgery classification based upon the anatomical location of the tumor. Sub-types of sacrococcygeal teratoma have different staging systems based on the size and growth of the tumor, lymph node involvement, and the presence of metastasis.

Classification

Classification Based Upon Anatomical Location

American academy of pediatrics surgery section system classifies sacrococcygeal teratoma depending on the anatomical location of the tumor. [1][2]

Stage Features

Type I

  • Predominantly external; with minimal pelvic involvement

Type II

  • Predominantly external; with significant intrapelvic growth giving "hour-glass" appearance

Type III

Type IV

  • Entirely pre-sacral; without external growth

Classification Based Upon Pathology

  • Benign : Mature[1]
  • Malignant : Immature
