Primary intraosseous mucoepidermoid carcinoma (PIOC) is an infrequent malignancy of the head and neck that exhibits diverse biological behavior. The rareness of the location for a salivary gland tumor and the clinical and radiographic manifestations, suggestive of an odontogenic lesion often pose a diagnostic challenge. We hereby report such a unique case of central mucoepidermoid carcinoma tha...

Medication-related osteonecrosis of the jaw (MRONJ) has been associated with use different drugs administered in treatment malignant neoplasms or metastases and antiresorptive therapies. Since 2010, denosumab, a monoclonal antibody whose mechanism action is to prevent activation RANK receptor on surface osteoclasts, jaw. Primary intraosseous squamous cell carcinoma (PIOSCC) rare neoplasm charac...

Dentigerous cysts constitute 20% of all odontogenic and are often located in the mandible maxilla. They seen at young ages men. Patients usually asymptomatic, diagnosis is established by dental radiographs routine scans. Surgery recommended for dentigerous because ameloblastoma, intraosseous mucoepidermoid carcinoma, or squamous cell carcinoma may develop from them. Generally transoral route pr...

BACKGROUND The term "primary intraosseous squamous cell carcinoma" was introduced in 2005 by the World Health Organization with three subcategories. Squamous cell carcinoma arising from the lining of an odontogenic cyst is one important rare subcategory of such lesions with an incidence of 0.01 to 0.02%. Furthermore, the appearance of such malignancy in an odontogenic tumor such as keratocystic...

The case of a 58-year-old man with a large primary intraosseous carcinoma (PIOC) of the mandible is presented. The tumour is rare, and the prognosis is usually poor. There are no specific histological characteristics of PIOC. Staining for basement membrane laminin could be a valuable aid in the differential diagnosis between PIOC and tumours of ameloblastoma origin.

Odontogenic carcinomas of the maxilla are classified as malignant ameloblastoma, ameloblastic carcinoma, or primary intraosseous carcinoma. The term ameloblastic carcinoma is used to describe those ameloblastomas in which there is histological evidence of malignancy in the primary, recurrent, or metastatic tumour. The maxilla is an unusual site for ameloblastoma. This report is of a patient wit...

Objective: To present a pictorial review on central mucoepidermoid carcinoma.
 Case report: Central carcinoma (CMEC), also known as intraosseous (IMEC), is an extremely rare disease (less than 2-4% of all MEC). However, CMEC the most frequent malignant salivary gland tumour found in locations. Due to this unusual location, diagnosis can be challenging. Therefore, often mistaken for other o...

BACKGROUND Mandibular pseudocarcinomatous hyperplasia is a rare and generally benign pathology. We report on one of these rare cases. CASE PRESENTATION The case history of a 73-year-old white man stated that he had a carcinoma of the oropharynx, which was primarily treated with radiotherapy and chemotherapy 4 years prior. As a result of radiotherapy he developed an osteoradionecrosis of his m...
