title: Multifocal bigerminal mature teratomas of the head and neck.
abstract: Teratomas and dermoids or hairy polyps of the head and neck are rare congenital tumours, often confused and reported to appear as single masses, that may cause upper aerodigestive tract impairment. Their histological classification, origin and embryological basis of development have been a topic of debate in the past and recent literature. We report a case of an infant presenting with a multifocal bigerminal teratoma in the nasopharynx and the neck, causing a deep neck infection, and discuss the unique clinicopathological aspects of this case.
