Congenital sialoblastoma (embryoma) associated with premature centromere division and high level of alpha-fetoprotein.

Sialoblastoma is a rare, locally aggressive, and potentially malignant perinatal salivary tumor that predominantly affects the parotid glands. To date, 29 cases of sialoblastoma have been reported. We report a further case of sialoblastoma diagnosed at 37 weeks of gestation presenting with novel findings that are the premature centromere division and a high level of alpha-fetoprotein.
