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	Predominantly internal; with intra-abdominal involvement
Type IV	Entirely pre-sacral; without external growth

Classification Based Upon Pathology

Benign : Mature^[1]
Malignant : Immature
