Schwannoma (neurilemmoma) is a benign neoplasm originated from the neural sheath and occurring most frequently in maxillofacial region. Intraosseous schwannomas are rare. The mandible is the most common site of occurrence for these lesions. We report a rare case of Intraosseous neurilemmoma of the mandible, with an emphasis on clinical, radiographic and pathological findings. The tumor, located mainly in the ramus region, presented as a soft tissue mass in the oral cavity, Multilocular, well-defined, and radiolucent lesion on plain radiography. Dilatation of the mandibular canal was identified. Plain radiography partly helped to identify the solid nature of the tumor. A biopsy was necessary to make the final diagnosis because of the relatively nonspecific nature of the lesion. The lesion was surgically removed and no evidence of recurrence was observed after 6 months.
Odontogenic myxoma (OM) is a rare and locally benign neoplasm of high aggressive behavior found exclusively in the jaws. OM commonly occurs in the second and third decade, its quite rare to find in maxilla that to invading the maxillary sinus completely. 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 case of OM of maxilla in a 13-year-old boy, which was previously diagnosed as fibrosseous lesion with the help of CT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
