Orthokeratinized Odontogenic Cyst : A Report of Three Clinical Cases

Abstract EN

The orthokeratinized odontogenic cyst (OOC) is a rare developmental odontogenic cyst that has been considered as a variant of the keratocystic odontogenic tumour (KCOT) until Wright (1981) defined it as a different entity.

Surgery is the usual treatment, and recurrence or association with Gorlin-Goltz syndrome has rarely been described.

In this report, we presented three cases of this pathology, and we review the principal clinical, histological, radiological, and therapeutic aspects.

Case 1.

A 73-year-old female presents with a slight swelling on the right mandible, associated with an unilocular well-defined radiolucent lesion.

Case 2.

A 27-year-old female presents with a painful mandibular swelling associated with an unilocular radiolucent lesion posterior to the 4.8.

Case 3.

A 61-year-old male was casually detected presents with an unilocular radiolucent lesion distal to the 4.8.

Conclusion.

The OOC is a specific odontogenic clinicopathological entity that should be differentiated from the KCOT as it presents a completely different biological behaviour.
