Recurrent keratocystic odontogenic tumor in the mandible: a case report and literature review.

Keratocystic odontogenic tumor is characterized by benign intraosseous neoplasm of odontogenic origin with high recurrence rates. Conservative or aggressive management has been suggested a method of treatment. Conservative approaches have some advantages in that they avoid adverse effects on the development of involved teeth and the jaw when the patient is young, although aggressive methods, including surgical resection, can be recommended considering the nature of the neoplasm. Here we report a case of a 7-year-old patient with a recurrent keratocystic odontogenic tumor treated by marsupialization for normal development of the involved teeth.
