Introduction: Desmoid tumors are very rare, benign fibrous neoplasms arise from the musculoaponeurotic structures throughout the body.   Case Report: The patient was a   seven-year old boy with a large mandibular mass growing over a period of six months. His CT-scan showed a large mass, 13 cm in diameter in the cheek area extending to the neck and trachea. Biopsy was compatible with desmoid fib...

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...

Salivary gland carcinomas are a rare and clinically diverse group of neoplasms among which mucoepidermoid carcinomas (MEC) are reported to be most frequently occurring. MEC display a variety of biological behaviors and variable natural history. We report a case of mucoepidermoidcarcinom. Histopathological features suggested intermediate grade mucoepidermoid carcinoma. Surgical resection was don...

BACKGROUND In general, Notch is a representative signal which controls morphosis and differentiation of cells, but its role in human odontogenic neoplasms, especially in ameloblastoma and its malignant counterpart, ameloblastic carcinoma, is not known. METHODS We examined Notch1 peptide and its gene (mRNA) in an ameloblastoma (case 1: 27-year-old female, right mandibular tumor) and an amelobl...

abstract   squamous cell carcinoma (scc) is the most common malignant tumors of oral cavity. the ratio of men to women is about 2: 1. generally, it   is admitted that 60% of carcinoma of the mandibular gingival are located in the posterior of premolars. gingiva is one of the less common sites of oral squamous cell carcinoma (oscc). due to the variable clinical and behavioral presentations, it c...

Plasma cell tumors are lymphoid neoplasms with an uncontrolled proliferation of B cells. These are divided into localized forms (solitary bone plasmocytoma -SBP- and extramedullary plasmocytoma -EP-) and disseminated forms (multiple myeloma-MM-). The SBP is a rare and controversial disease. The aim of this article is the analysis of this entity based on the presentation of a 64-year-old man wit...

Schwannomas (neurilemmomas) are benign neoplasms derived from Schwann cells of the neurilemma and appear most frequently on the auditory nerve or peripheral nerves of the skin. They arise in the oral and maxillofacial region infrequently, and very rarely in the center of the jaw. We herein present a case of a rare mandibular intraosseous schwannoma derived from the main trunk of the inferior al...

Odontogenic tumors contain a heterogeneous collection of lesions that are categorized from hamartomas to benign and malignant neoplasms of inconstant aggressiveness. Odontogenic tumors are usually extraordinary with assessed frequency of short of 0.5 cases/100,000 population for every year. The lesions such as odontogenic tumors are inferred from the components of the tooth-structuring contrapt...

Calcifying epithelial odontogenic tumors are rare odontogenic neoplasms that account for approximately one percent of all odontogenic tumors. Extra osseous variant is very rare with very few cases being reported in literature Peripheral Calcifying epithelial odontogenic tumor (CEOT) commonly resemble oral hyperplastic or reactive lesions and are histologically similar to their intraosseous coun...
