Central mucoepidermoid carcinoma (MEC) poses a diagnostic challenge because of its rarity and histological overlap with glandular odontogenic cyst (GOC). In MEC of both salivary glands and jaws, MAML2 arrangement has been well known as the specific gene alteration. We report a case of central MEC arising from GOC diagnosed by MAML2 fusion gene. A 57-year-old male presented a multilocular cystic lesion in left molar region of the mandible. Histopathologically, multiple cysts lined by thin cuboidal or non-keratinized squamous epithelium with small duct-like structures, mucous cells and ciliated cells were present...

BACKGROUND: Glandular odontogenic cyst (GOC) demonstrates a significant predilection toward localized biologic aggressiveness and recurrence. GOC shares certain histopathologic features with intraosseous mucoepidermoid carcinoma (IMEC). The current investigation evaluates a group of recurrent, biologically aggressive GOCs to determine if any cases demonstrated unique histologic features or Mastermind - like2 (MAML2) rearrangements common to IMEC. METHODS: Microscopic slides from eleven previously diagnosed GOGs were stained with hematoxylin and eosin and assessed by two study participants for ten classic histopathologic features required to establish a diagnosis of GOC...

Decompression has been considered a valuable tool for odontogenic cystic lesions to minimize cyst size with low morbidity and recurrence. However, whether decompression has a role in regulating stem cell properties of orofacial bone marrow stromal cells (BMSCs) around the cysts has not been fully investigated. The present study compared the stem cell marker profile and osteogenic differentiation potential of orofacial BMSCs prior to and following marsupialization (pre‑BMSCs vs. post‑BMSCs) in the same individuals...

A calcifying cystic odontogenic tumor (CCOT) is a proliferation of odontogenic epithelium and scattered nests of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass. It was previously described by Gorlin et al in 1962 as a calcifying odontogenic cyst. Dentigerous cysts are developmental odontogenic jaw cysts, commonly manifesting in the second and third decades of life. The present study reports an asymptomatic case in a 13-year-old boy who was referred to the outpatient clinic of the Osaka Dental University Hospital (Osaka, Japan) for additional investigation of an area of radiolucency in the lower right jaw...

OBJECTIVES: Odontogenic keratocyst (OKC), also known as keratocystic odontogenic tumor (KCOT), has clinical significance due to its high incidence as well as high recurrence rate after surgical enucleation. Current clinical management for OCK is entirely dependent on surgical approach. While various genetic alterations, such as PTCH1 mutation and loss of heterozygosity in tumor suppressor genes, have been reported, the molecular background of OKC is not well-understood. Although recent identification of BRAF V600E mutation and subsequent activation of mitogen-activated protein kinase (MAPK) pathway in ameloblastoma and odontogenic tumors provide additional options with targeted therapeutics, the molecular background of OKC is not well understood...

An ameloblastic fibro-odontoma (AFO) is a rare mixed odontogenic tumor with histologic features of an ameloblastic fibroma in conjunction with the presence of dentin and enamel. It usually appears as a well-circumscribed radiolucency with radiopaque foci and slow growth and is commonly seen in children and young adults. A 13-year-old boy presented with an asymptomatic swelling in the posterior right region of the mandible and the right ascending ramus. The clinical, imaging, and histopathologic findings confirmed the diagnosis of an AFO...

The dentigerous cyst (DC) is the most common type of developmental odontogenic cyst. It is usually asymptomatic and associated with the crown of an unerupted or impacted tooth. However, after a long duration, it is likely to cause significant bone resorption, cortical expansion, and tooth displacement. This report presents a large infected DC in the mandible of a 12-year-old female patient. The DC was located inferior to badly decayed primary molars and surrounded three impacted permanent teeth: canine, first premolar, which had a dilacerated root, and second premolar...

The aim of the study was the assessment of effectiveness of endoscopic techniques in the treatment of extensive odontogenic cysts. Endosurgery for diagnostic and therapeutic purposes was used in 67 patients with odontogenic cysts of the jaws: 23 follicular cysts, 19 radicular cysts, 6 residual cysts, and 19 keratokists. The results prove that the developed methods of endovideosurgery of odontogenic cysts have low invasiveness, provide an optimal healing of bone tissue and reduce postoperative complications.

OBJECTIVES: Odontogenic tumors (OT) represent a specific pathological category that includes some lesions with unpredictable biological behavior. Although most of these lesions are benign, some, such as the ameloblastoma, exhibit local aggressiveness and high recurrence rates. The most common types of ameloblastoma are the solid/multicystic (SA) and the unicystic ameloblastoma (UA); the latter considered a much less aggressive entity as compared to the SA. The microRNA system regulates the expression of many human genes while its deregulation has been associated with neoplastic development...

The 4 < sup > th < /sup > edition of the World Health Organization (WHO) Classification of Head and Neck Tumors was published in January 2017. The edition serves to provide an updated classification scheme, and extended genetic and molecular data that are useful as diagnostic tools for the lesions of the head and neck region. This review focuses on the most current update of odontogenic cysts and tumors based on the 2017 WHO edition. The updated classification has some important differences from the 3 < sup > rd < /sup > edition (2005), including a new classification of odontogenic cysts, 'reclassified' odontogenic tumors, and some new entities...

This article was designed to report the clinical case of the radicular cyst localized in the maxillary sinus of the 23 year-old man that had been detected before the surgical intervention was undertaken for its treatment. In the preceding visits of the patient to other medical settings, this condition was misinterpreted as a genuine (rhinogenic) cyst. It accounted for the choice of the inadequate surgical strategy for the management of this pathology. As a result, the patient experienced two relapse episodes of the disease...

Orthokeratinized odontogenic keratocyst (OOC) was first identified as orthokeratinized variant of odontogenic keratocyst in 1981 by Wright, due to its different histology and relatively low recurrence rate. Parakeratinized odontogenic cyst is now considered as keratocystic odontogenic tumor (KCOT) owing to its neoplastic nature. Although rare, calcification in the form of dystrophic calcification, dentinoid and cartilage has been reported in KCOT, but calcification in OOC is extremely rare and no case in English literature has been reported so far...

Odontogenic keratocysts (OKCs) are locally infiltrative odontogenic cysts that are usually diagnosed during routine radiographic examinations. Therefore, it is critical that dental practitioners, in particular orthodontists, recognize and diagnose OKCs to recommend appropriate treatment. This report describes a patient whose OKC was not initially identified during orthodontic pretreatment. In addition, this report discusses the clinical and radiographic features of OKCs, as well as the differential diagnoses of these lesions...

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...

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...
