title: Arteriovenous malformation of the mandible: report of a case with a note on the differential diagnosis.
abstract: Arteriovenous malformations are extremely rare conditions that can result from congenital or acquired abnormalities in the structure of blood vessels; they are potentially fatal. Arteriovenous malformations may be asymptomatic or may show various signs and symptoms including soft tissue swelling, pain, changes in skin and mucosal color, erythematous and bleeding gingiva, bruit, and paresthesia. Radiographically, there are no pathognomonic features. The present case illustrates an arteriovenous malformation in a 16-year-old Hispanic female. The case report is unique because the malformation was previously interpreted as a pathosis of pulpal origin and was initially treated as such, although the tooth showed no gross or radiographic dental caries. A broad view of the diagnostic imaging, radiographic differential diagnosis, treatment, and histopathologic description is also presented.
