Ameloblastomas are rare tumors that arises from the odontogenic epithelium. Although benign and slow growing, an extensive lesion may cause airway obstruction, making bag-mask ventilation intubation a significant challenge. Here, we present 54-year-old male in respiratory distress with 18x15x13 cm submandibular mass causing compromise. The tumor was extensive, occupying most of oral cavity. Una...

BACKGROUND Odontomas are the most common benign odontogenic tumors (especially in children and adolescents) and consist of odontogenic ectomesenchyma and odontogenic epithelium with the formation of dental hard tissues. They are also simply considered hamartomas. The WHO Classification defines them as complex and compound odontomas. The diagnosis is often occasional, in conjunction with x-ray r...

Keratocystic Odontogenic Tumor has been defined by the World Health Organization as a benign intraosseous neoplasm of odontogenic origin with characteristic lining of the parakeratinized squamous epithelium. Due to variable features of this lesion pertaining to clinical and biologic behaviour, this tumor is been studied extensively even today with respect to its molecular aspects to resolve man...

The ameloblastic fibro-odontoma is a rare mixed odontogenic tumor. It occurs predominantly in children and young adults with no sex predilection and locates most often in the posterior segment of the mandible. A painless swelling is the most common clinical sign. Radiologically, ameloblastic fibro-odontoma shows a circumscribed radiolucency, which contains radio-opaque foci of various sizes and...

Odontogenic tumor is one of the tumors of great significance in the oral region. The process of its development remains obscure. It seems very advantageous in the investigation of dontogenic tumor to establish experimental models in laboratory animals. However, experimental attempts of induction of odontogenic tumor have not been very successful. In recent years, the carcinogenic property of ni...

Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin composed of odontogenic epithelium in a variety of histoarchitectural patterns. Most cases are in females and have a striking tendency to occur in the anterior maxilla. However, AOT of the maxillary antrum is extremely rare. A 25-year-old female presented with a large radiolucent lesion associated with the crown of a...

Calcifying epithelial odontogenic tumour (Pindborg tumour) is a rare benign neoplasm with a poorly understood histogenesis. This report describes a single case of a maxillary calcifying epithelial odontogenic tumour including immunohistochemical analysis. The vast majority of tumour cells were positive for CK5/6 and p63. Furthermore, basal cells also displayed moderate reaction for vimentin and...

Calcifying epithelial odontogenic tumors are benign odontogenic neoplasms whose occurrence in the maxillary sinus is rare. Maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures. We report a case of a large calcifying epithelial odontogenic tumor of the maxilla, involving the maxillary sinus in a 48-year-old woman. The tumor was largely intraosse...

Despite Ameloblastic fibroma (AF) is a rare odontogenic tumour, it occurs predominantly in children and therefore remain an important diagnostic consideration.1 It usually arises from the mandibular dentition although it can arise in maxilla.2 AF consists of odontogenic ectomesenchyme resembling the dental papilla and epithelium resembling dental lamina and enamel organ without dental hard tiss...

Extra-osseous odontogenic tumors are rarely observed. However, it is widely accepted that the remains of odontogenic epithelium entrapped in the oral soft tissues may be a possible source for peripheral odontogenic tumors differentiation. Peripheral developing odontoma is considered exceptionally rare, since few similar cases are described in the English-related literature under diverse nomencl...
