On autopsy, a pedunculated mass arising from the posterior end of palate through the basisphenoid, measuring 9.5 x 7.5 x 6 cm, was seen protruding from the oral cavity [Figure 1a]. Microscopically, the mass was composed of mature components of all the three germ cell layers comprising stratified squamous epithelium, nervous tissue, intestinal epithelium, respiratory epithelium, cartilage, bony tissue, skeletal muscle, adipose tissue and blood vessels [Figure 1b, c]. Foci of immature neuroepithelial components comprising small round cells forming rosettes and tubules were also found [Figure 1d].
