title: Oral teratomas: a report of 5 cases.
abstract: OBJECTIVE
  To present a case series of 5 patients with oral teratomas, discussing the treatment and follow-up.
  
  
  METHODS
  Five patients (4 girls and 1 boy) with oral teratomas presented at the Maxillofacial Surgery Department of a University Hospital with a reference population of 1,000,000 between 1980 and 2002. The associated lesions, clinical examination, histopathology, treatment and follow-up were registered and described. The newborns presented associated congenital malformations such as cleft palate, bifid tongue, dorso-nasal fistula and nasal dermoid cyst. In all 5 cases the tumor mass was excised at its base with surrounding normal tissue under general anesthesia combining conventional and electric scalpels. Histological analysis resulted in different compositions of multiple tissues typical of teratomas. After a mean follow-up of 8 years no sign of tumor recurrence had been detected.
  
  
  CONCLUSIONS
  Teratomas were a rare finding within a large population of newborn patients. Five tumors were excised and histologically diagnosed as teratomas. No recurrence occurred after 8 years of follow-up.
