Sacrococcygeal teratoma

Abstract

Sacrococcygeal tumour (SCT) is the commonest neoplasm seen in the newborn. A 'teratoma' (derived from the Greek language meaning "Monster")-is best defined as a neoplasm arising from primitive tissues which originated from all three embryonic germ cell layers-endoderm. Mesoderm and ectoderm. SCT occurs in 1:30,000-40,000 births according to recent publications emerging from the UK and Europe (Ayed et al. Prenat Diagn. 35: 1037-47, 2015; Pauniaho et al. Acta Paediatr. 102:e251-6, 2013). There is often a female preponderence (3:1) except in familial cases of SCT which may have an equal gender distribution (M:F = 1).
