Abstrakt: Introduction: "Vascular malformations" comprise a group of lesions, formed by an anomaly of angiovascular or lymphovascular structures and are known as a clinical entity since the mid-18th century. Arteriovenous malformation (AVM) is a high-flow vascular malformation characterized by direct communication between arteries and veins, lacking normal capillary network. They comprise 14.3% of vascular malformations and anatomically in the head and neck region account for only 8.1%. AVM are usually congenital. Acquired are reported to occur due to trauma or hormonal changes. AVM present a therapeutic challenge because of their hemodynamic characteristics and their modality of growth. Surgical resection is often associated with extensive blood loss and an incomplete resection frequently leads to re-growth of the lesion often larger than its original size. Case Report: A 65-year-old male reported with complaint of bleeding from the swelling on upper lip since 1 month. Patient was a trumpet blower by occupation. Examination revealed everted upper lip with oval swelling of size approx. 3 x 3 cm and was pulsatile in nature. Overlying mucosa was pink-red in color with central ulceration and bleeding points. Contrast enhanced computed tomography (CECT) angiography revealed AVM like features confirmed by histopathology. Conclusion and Summary: AVMs can be acquired as a result of chronic trauma as in this case. AVMs though rare in oral cavity, when present are persistent and progressive in nature and can represent a lethal benign disease. The purpose of this case report is to emphasize early diagnosis and prompt treatment of such cases. [ABSTRACT FROM AUTHOR]
