Abstract Objective Orthokeratinized odontogenic cyst is a rare developmental odontogenic cyst of the jaws. It is a less aggressive intraosseous cyst identified by an orthokeratinized epithelium. Case Report A 50-year-old male patient with the chief complaint of swelling in the anterior part of his face, and, intraorally, there was diffuse swelling in the palatal cortex. On panoramic radiography, there was a well-defined unilocular radiolucency on the right side of the maxilla and palatal cortical expansion, and thinning of the buccal and palatal cortexes was observed. The histopathological examination revealed a pathologic cyst that was lined by a thick orthokeratinized epithelium. Therefore, the diagnosis was orthokeratinized odontogenic cyst. Conclusion The orthokeratinized odontogenic cyst displays characteristic clinical, histopathological, and biological features that differ significantly from those of keratocystic odontogenic tumor (KCOT), but it has a better prognosis and lower recurrence rate. Thus, other radiolucent lesions of the jaws, including keratocystic odontogenic tumor (KCOT), must be considered in the differential diagnosis.

Epithelial Odontogenic Tumor

We report a case of recurrent Pindborg tumor (calcifying epithelial odontogenic tumor) of the maxilla. The patient was a 34-year-old woman who had been previously diagnosed with Pindborg tumor and treated with curettage. She was subsequently referred to us for evaluation of nasal obstruction. Examination revealed the presence of a mass lesion in the right nasal cavity and right maxilla, which was identified as a recurrence of her earlier Pindborg tumor. The patient was treated with maxillectomy with orbital preservation. Pindborg tumor is a rare odontogenic tumor; when it does occur, it is more often seen in the mandible than in the maxilla. While this tumor is often treated with curettage alone, the aggressive nature of the recurrence in our patient necessitated radical surgery. We report this case to highlight the need to be suitably aggressive in treating these types of tumors in order to avoid recurrence.

Desmoplastic ameloblastoma (DA) is one of the 6 histopathological subtypes of ameloblastoma. Hybrid lesions in which histopathologically conventional ameloblastoma coexists with areas of DA are rare. A 40-year-old male was referred to our hospital complaining of a swelling in the right premolar region of the mandible. A panoramic radiograph showed an area of radiolucency with a well-defined corticated border, whereas computed tomography revealed a unilocular radiolucent lesion and buccal expansion together with cortical perforation. The lesion was treated via enucleation and curettage of the marginal bone and fenestration. A histopathological examination showed a hybrid ameloblastoma with a pronounced desmoplastic pattern and follicular changes. The patient’s postoperative course has been favorable up to now, and no marked changes have been observed. We presented a case of hybrid ameloblastoma and reviewed the 36 reported cases of hybrid ameloblastoma that have been reported in the English literature.

Orthokeratinized Odontogenic Cyst

ABSTRACT Orthokeratinized odontogenic cyst (OOC) was first identified as the rare variant of keratocystic odontogenic tumor (KCOT) for its different histopathology and rare recurrence which was reclassified by WHO in 2005. The orthokeratinized odontogenic cyst is a distinct clinicopathologic entity and is histologically characterized by a thin, uniform, epithelial lining with orthokeratinization and a subjacent granular cell layer. The basal cells are usually cuboidal or flattened. OOC in maxilla is rare. This article presents a case of 56-years-old male patient with OOC in left maxilla. The clinical, radiographic and histological features of the cyst are discussed in this case report.
