Arteriovenous malformations (AVM) are usually observed on the skin, but they can also rarely affect the visceral organs and the maxillofacial area. In the maxillofacial area, these lesions can spread and they are potentially dangerous, as a biopsy or even a simple tooth extraction can lead to a catastrophic haemorrhage that may eventually cause death. There are several indications for the treatment, including age, size and type of vascular malformation. The purpose of this report is to describe an AVM on the maxilla, first diagnosed as an epulis, which has been treated for several years as a chronic local periodontitis. The lesion was finally stabilised after an antibiotic therapy. Improved knowledge of the development of these lesions and collaboration between dentists, radiologists and surgeons are necessary to improve the diagnosis and treatment of vascular malformations.
