Synchronous cystic lesions in the jaws: case reports

The association of odontogenetic lesions affecting the maxillary bones in the same patient is rare. The aim of this paper is to report two cases of synchronous lesions affecting the same patient. In the first case, the patient presented an odontogenic keratocyst in the jaw and a nasopalatine duct cyst, and in the second case, the patient presented an ameloblastoma in the jaw and nasopalatine duct cyst. Both cases were treated through the total removal of the lesions, microscopically revealed the respective diagnoses and now they are being controlled, with absence of recurrence after four years.
