Sumario:Objective: Intraosseous Arteriovenous malformation (AVM) is a vascular hamartoma with almost 50% of cases occurring in the head and neck. These lesions are of great importance as they may cause massive bleeding during tooth extraction and surgeries. Case report : A 33 year old female complained of swelling and gingival bleeding on the right side of the maxilla and hard palate. The swelling was noticed during pregnancy and the patient underwent a surgical excision 6 months after labor. The specimen was submitted for histological examination. An intraosseous AVM presenting in maxilla was diagnosed. Conclusion: Although rare, intraosseous AVM may occur. The role of pregnancy and hormonal changes is still controversial. Clinical, radiographic and histological characteristics of AVM should be thoroughly assessed before surgical excision.
