Teratoma of the tongue is an extremely rare tumour of the oral cavity, which is composed of ectoderm, mesoderm and endoderm with differentiation to identifiable tissues and organs. We described a female neonate with a giant teratoma of the tongue and an incomplete cleft palate. ⋯ Histopathologically, it consisted of stratified squamous epithelium on the surface, and ciliated prismatic epithelium, cartilage and neuroglial tissue. Two years after excision there was no sign of recurrence.
