Abbreviations
- Sacrococcygeal teratoma (SCT)
Synonyms
- Teratoma, germ cell tumor of coccyx
Definitions
- Teratomas made up of various parenchymal cell types from > 1 germ layer, usually all 3
- Tumors may contain hair, teeth, cartilage, & fat, amongst other tissues
- SCT arises from coccyx, potentially grows both internally & externally (with latter more common)
- Both benign & malignant varieties
- Teratomas made up of various parenchymal cell types from > 1 germ layer, usually all 3
