title: Mid-cervical malignant pleomorphic adenoma presenting with upper airway obstruction.
abstract: The case of a 1 year and 6 months old girl with pleomorphic adenoma arising from the upper middle part of the neck is reported. Although the tumor invaded the hyoid bone, it was removed completely and symptoms of upper airway obstruction disappeared. We suspect it may have originated from thyroglossal duct structures.
