Cystic mass at the suprasternal notch of a newborn: congenital suprasternal dermoid cyst.

We report a case of a newborn female with an unusual suprasternal simple cystic mass found to be a dermoid cyst. Dermoid cysts of the head and neck are rare lesions, but a midline location is characteristic for these congenital masses. A dermoid cyst should be high on the list of differential diagnoses given a unilocular midline cyst in a neonate even if no fat elements are demonstrated on imaging studies.
