Fetopathology examination revealed a tumor arising from the nasopharynx / cavum, protruding through the oropharynx and oral cavity, and also invading the central base of the skull around the pituitary fossa. The fetus itself had normal morphology otherwise, and a mild IUGR (-2 WG).
Histology of the tumor showed a mix of epithelial, bone, chondroid and immature nervous tissues.
