Midline segmental odontomaxillary dysplasia.

Segmental odontomaxillary dysplasia (SOD) is a rare developmental disorder of the maxilla, characterized by variability of its clinical and radiological features and may mimic other fibro-osseous lesions. Clinically, the disorder is often diagnosed in early childhood due to a unilateral buccolingual expansion of the posterior alveolar process, gingival enlargement, absence of one or both premolars in the affected region, delayed eruption of the adjacent teeth, and malformations of the primary molars. We describe a rare case of a SOD in a 19-year-old female comprising findings similar to earlier reports, but for the first time SOD is reported along midline. She presented with pre-maxillary enlargement and abnormal pattern of eruption of anterior maxillary permanent teeth. Radiographic imaging showed abnormal bony trabeculation. Histopathologic findings showed characteristic features of SOD. We herein report a case of this rare unusual anomaly and review the literature. Clinicians should be aware of its presence when encountering patients presenting with facial asymmetry unresponsive to treatment.

Schwannoma causing resorption of zygomatic arch.

Schwannoma (also known as neurilemmoma, peripheral glioma and peripheral nerve sheath tumor) is a common, histologically distinctive, benign, usually encapsulated, peripheral nerve tumor of Schwann cell origin. Schwannomas can appear anywhere in the body, but are more frequently reported in the head and neck with an incidence of 25-48% in maxillofacial region. Resorption of bones due to schwannoma is rarely noticed in maxillofacial region. We hereby present a case report of schwannoma in a 35-year-old female, causing resorption of zygomatic arch along with review of literature.

Odontogenic myxoma of the maxilla: A report of a rare case and review on histogenetic and diagnostic concepts.

Odontogenic myxoma (OM) is a rare and locally invasive benign neoplasm (comprising of 3-6% of all odontogenic tumors) found exclusively in the jaws. OM commonly occurs in the second and third decades, and the mandible is involved more commonly than the maxilla. The lesion often grows without symptoms and presents as a painless swelling. The radiographic features are variable, and the diagnosis is therefore not easy. This article presents a rare case of OM occurring in the maxilla of a 37-year-old female patient with a brief review of the pathogenesis, clinical, radiological, histopathological, ultrastructural and immunohistochemical characteristics of OM.

Pattern of bear maul maxillofacial injuries in Kashmir.

OBJECTIVE: Bears are strong and agile wild animals that defend themselves, their young ones and their territory, if they feel threatened. Conflicts between humans and bears are common in bear-prevalent areas of the world. Our valley, which is surrounded all around by forests, is a habitat for black bears (U. thiabetanus) only. Maulings inflicted by these black bears are catastrophic events and such attacks have increased considerably in the recent past due to merciless deforestation. The rising incidences of such attacks, especially in maxillofacial region, have urged our department to undertake a study of such attacks and injuries. MATERIALS AND METHODS: The present study is both a retrospective and prospective study of 200 patients of bear maulings who were admitted and treated in the Department of OMFS, Govt. Dental College, Srinagar, from January 2005 to October 2009. RESULTS: Majority of the patients were from villages. Most of them belonged to fourth decade and majority was males. Black bears only were involved in all the encounters. Claws, paws and combination of both, were the used for attack. In majority of cases, no defense was used for the termination of attack. All the patients had soft tissue injury, deep lacerations, facial viscera, eyes, salivary glands and facial nerve commonly involved.

Multiple Myeloma presenting as Gingival mass.

Maxillofacial presentations in patients with multiple myeloma are not uncommon, but multiple myeloma is often overlooked. Because the symptoms are various, it is very difficult to diagnose multiple myeloma in the oral and maxillofacial region. On the basis of the pathologic and clinical findings, the patient was diagnosed with multiple myeloma. Hematologic screening and a radiographic survey further confirmed the diagnosis.

Head and neck teratomas.

Teratomas are complex lesions composed of diverse tissues from all 3 germinal cell layers and may exhibit variable levels of maturity. Head and neck teratomas are most commonly cervical with the oropharynx (epignathus) being the second commonest location. In this article, clinical presentation, behaviour and associated significance of head and neck teratomas have been highlightened. Because of their obscure origin, bizarre microscopic appearance, unpredictable behaviour and often dramatic clinical presentation, a dental surgeon or a dental specialist should be aware of their clinical presentation and pathology.
