We conducted a retrospective study to analyze the histologic and immunohistochemical findings in three main types of odontogenic cyst. We studied 90 archived cystic jaw lesions: 30 dentigerous cysts, 30 keratocystic odontogenic tumors, and 30 radicular cysts. The cyst types were identified on the basis of clinical, radiologic, and histopathologic findings. Immunohistochemical analyses included staining with Ki-67, p53, epidermal growth factor receptor (EGFR), cytokeratin (CK) 8, CK14, CK17, and CK18. Cell immunopositivity was evaluated for the entire epithelium...

Calcifying epithelial odontogenic tumor (CEOT) is a rare, benign, odontogenic tumor arising from the odontogenic epithelium and accounts for approximately 1% of all odontogenic tumors. Clear cell variant of CEOT is a distinct entity and has more aggressive biological behavior and higher chances of recurrence. Here, we present a unique case of clear cell variant of CEOT involving the left side of the maxillary alveolus in a 73-year-old female patient with thorough clinical, radiological, and histological details...

The botryoid odontogenic cyst (BOC) is a rare, locally more aggressive variant of the usually indolent lateral periodontal cyst (LPC) and gingival cyst (GC). A recent case of BOC provided an opportunity for an exploratory study on the causes of its more aggressive behavior. The limited objective was to see if the BOC was sufficiently different from the other cysts to warrant an investment in a large study. Sections of neutral buffered formalin fixed, paraffin-embedded tissues from the BOC and archival specimens of four GCs, four LPCs and three odontogenic keratocysts (OKCs) were stained using immunohistochemistry for Ki-67, a marker of proliferating cells, caspase-3, a marker of cells undergoing apoptosis, tumor suppressor p53, and the apoptosis inhibitor BCL2...

Several benign pathologic entities that are commonly encountered by the oral and maxillofacial surgeon remain controversial. From etiology to treatment, no consensus exists in the literature regarding the best treatment of benign lesions, such as the keratocystic odontogenic tumor, giant cell lesion, or ameloblastoma. Given the need for often-morbid treatment to prevent recurrence of these lesions, multiple less-invasive treatments exist in the literature for each entity with little agreement. As the molecular and genomic pathogenesis of these lesions are better understood, directed treatments will hopefully lessen the contention in management...

Odontogenic myxomas are rarely occurring, slow-growing, asymptomatic, and locally aggressive odontogenic tumors with high rate of recurrence, mainly of ectomesenchymal origin. Three-dimensional imaging techniques can be used to diagnose such pathological lesions, but have limited use as they are not cost-effective and are selectively available for better outcome. Following is a case report of OM of a 5-year-old child with a brief discussion on its diagnosis and management. HOW TO CITE THIS ARTICLE: Mukherjee CG, Mukherjee U, Bansal A, Jha A...

INTRODUCTION: The adenomatoid odontogenic tumor (AOT) associated with odontoma has been described as a new entity with overlapping features of adenomatoid-like structures and odontoma. Presentation of the case: We report the second case of AOT associated with odontoma in the posterior maxillary region. A 22-year-old patient presented expansion of the vestibular and palatine cortical wall of maxilla. Radiographic examination and computed tomography confirmed erosion of maxillary walls, root resorption, displacement of a neighboring tooth and radiopacities within the lesion...

INTRODUCTION: Odontomas are considered as benign tumors of odontogenic tissue origin and are more over non-aggressive. They can also be categorized as hamartomas and are a result of developmental malformation of odontogenic tissues. As the name suggests, they are composed of mature tooth substances. They possess limited and slow growth potential and are well differentiated. They can be ectodermal, mesodermal or mixed in origin. Mixed variety may be further divided into compound or complex depending upon their radio-graphical resemblance to the tooth...

AIM: This study aimed at evaluating histological features of 52 cases of calcifying odontogenic cyst (COC), which is an uncommon benign odontogenic lesion. The World Health Organization (WHO) classified COC as a neoplasm and used the term calcifying cystic odontogenic tumor (CCOT) for benign cystic type and the dentinogenic ghost cell tumor (DGCT) for the benign solid-type lesions. There is no agreement regarding COC classification. MATERIALS AND METHODS: A total of 52 cases of COC were selected and reviewed from the archive of the Pathology Department of Taleghani Educational Hospital, Tehran, Iran...

Squamous odontogenic tumor is a rare benign epithelial odontogenic tumor of the jaw. Most are solitary lesions, although rare multifocal lesions have been described. Maxillary lesions have more aggressive behavior. Because of their benign character, these lesions are usually treated using a conservative surgical approach with curettage and surgical enucleation. This report describes the case of a 29-year-old woman with multifocal lesions who was initially treated with conservative surgical therapy. Early recurrence 6 months after surgery prompted more aggressive resection...

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic neoplasm of the jaws. Although clear cells have been reported in approximately 8% of cases of CEOT, the exact nature of these cells in clear cell calcifying epithelial odontogenic tumor (CCEOT) has not been elucidated. Presence of clear cells in CEOT may confer a more aggressive behavior to the lesion and a tendency for recurrence and metastatic spread. We report of a case of CCEOT in a 63 year old female patient which was first treated with enucleation; however recurrence prompted a segmental resection along with coronoid and condyle...

Peripheral odontogenic myxoma is a rare odontogenic tumor representing an extra osseous counterpart of central odontogenic myxoma. It is commonly seen in gingiva between the 3rd and 4th decades of life and appears predominantly in females. Compared to central odontogenic myxoma, it is a less aggressive, slow-growing lesion with a low recurrence rate. However, close postoperative follow-up is required because of the unlimited growth potential of incompletely removed lesions. It shares many features with other soft tissue myxoid proliferations occurring in the oral cavity and hence needs to be differentiated from them...

Keratocystic odontogenic tumor (KCOT) is a benign odontogenic tumor with an aggressive behavior and high recurrence rate. The most common site of predilection is the posterior mandible. In contrast, KCOTs occurring in the maxillary region are relatively rare. However, the maxillary involvement poses a greater and increased threat, due to proximity to vital structures such as maxillary sinus, orbital floor, and infratemporal fossa. This report presents such a case of KCOT involving the maxillary sinus eroding the floor of the orbit and provides an account of the factors that need to be considered during management...

We describe a 13-year-old boy with recurrence of an odontogenic myxoma of the mandible. We review the existing published literature on the lesion, emphasizing the similarities and differences among lesions in the differential diagnosis. Odontogenic myxoma is an uncommon benign tumor that mainly affects the mandible, with a peak incidence in the second to fourth decades of life and predilection for the female sex. Clinical, radiological, and histopathological features should be considered when making a diagnosis...

Cherubism is a rare autosomal dominant condition affecting the jaws and caused by mutations in the gene encoding for the adapter protein SH3BP2 that maps to chromosome 4p16.3. Cherubism is characterized by symmetrically developing bone lesions in the maxilla and mandible. The lesions have been radiographically and histopathologically well-described. Here, we present a family with cherubism with two of its members featuring odontogenic tumorous proliferations in association with persistent central giant cell lesions (CGCL)...

Ameloblastic fibrodentinoma is a benign odontogenic tumor belonging to the category of "odontogenic epithelium with odontogenic ectomesenchyme" along with recognition of induction in the form of dentin in atypical or dysplastic forms. The biological behaviour of ameloblastic fibrodentinoma is not very different from ameloblastic fibroma; hence, it is treated similarly by conservative procedures. It is important to understand the histopathogenesis of these rare tumors. Though rare, they are an independent entity awaiting recognition...
