Decompression is considered an effective treatment for odontogenic cystic lesions in the jaw. A variety of decompression devices are successfully used for the treatment of keratocystic odontogenic tumors, radicular cysts, dentigerous cysts, and ameloblastoma. The purpose of these devices is to keep an opening between the cystic lesion and the oral environment during treatment. The aim of this r...

Ghost cell odontogenic carcinoma (GCOC) is an exceedingly rare malignant tumor on the spectrum of already uncommon odontogenic or dentinogenic tumors. We describe here the case of metastatic GCOC in a patient with a history of recurrent dentinogenic ghost cell tumor of the mandible, now presenting with bilateral pleural effusions. We will discuss typical histopathologic and histochemical featur...

Keratocystic odontogenic tumors (KCOTs) are certainly among the most studied lesions in oral pathology, which is not a surprise considering their perplexing clinical behavior and complicated mechanism of pathogenesis. In fact, the specific KCOT features are the reason for numerous discussions regarding the true nature and classification of these lesions, which are still debated in the scientifi...

Introduction Odontogenic epithelium is responsible for tooth development under physiologic conditions and can give rise to tumors or cysts in the jaws (1-3). Ameloblastoma is the most frequently encountered tumor arising from odontogenic epithelium and is characterized by a benign but locally invasive behavior with a high tendency to recur (2, 4). Histologically, ameloblastoma shows considerabl...

Objective: This study aimed to assess osteopontin expression following immunohistochemical staining of odontogenic cysts and tumors. Methods: A systematic review was conducted based on PRISMA Statement. The literature search carried out through PubMed, Scopus, Science Direct databases, covering all the articles published up October 2021, using a combination key terms ‘osteopontin’, ‘odontogenic...

Odontomas are benign non-aggressive odontogenic tumors and most commonly regarded to be intraosseous lesions of jaw bones. A facial extraoral peripheral odontoma with an intriguing ectopic appearance is uncommon. visual, radiographic, histological confirmation complex facilitates the treatment surgical excision, which inhibits creation fistula preserves esthetics.

Adenomatoid odontogenic tumor (AOT), constituting approximately 3-7% of all odontogenic tumors is described as a rare benign epithelial tumor of odontogenic origin. It is composed of odontogenic epithelium arranged in a variety of histoarchitectural presentations and closely resembles an ameloblastoma. AOT is mostly asymptomatic and is usually associated with impacted teeth in maxillary anterio...

The calcifying epithelial odontogenic tumor (CEOT) is a rare benign neoplasm; it comprises only 0.6 % to 1.7 % of all odontogenic tumors. Most cases involve the posterior mandible; there have been few reported maxillary cases. Although its biological behavior is relatively indolent, maxillary lesions tend to grown rapidly and not be circumscribed. Treatment of the CEOT consists of surgical remo...

Ameloblastoma, a benign neoplasm of jaw bones is the most common of all odontogenic tumors. Its pathology is generally well understood and is easy to diagnose. This article presents a rare case of an ameloblastoma with atypical features depicting an example of the diagnostic difficulty posed by some ameloblastomas and briefly reviews the classification and literature of odontogenic malignancies...
