"Vascular malformations" comprise a group of lesions, formed by an anomalous proliferation of angiovascular or lymphovascular structures. Arteriovenous malformations (AVMs) are high-flow malformation, characterized by direct communication between arteries and veins, lacking normal capillary network. AVMs are usually congenital. Acquired AVMs are reported to occur due to trauma or hormonal changes. Acquired AVMs, though rare in oral cavity, when present are persistent and progressive in nature and can represent a lethal benign disease. They are often associated with extensive blood loss, and an incomplete resection frequently leads to regrowth of the lesion often larger than its original size. We present a rare case of an acquired AVM diagnosed on contrast-enhancing computed tomography angiography and histopathology in a 65-year-old professional trumpet blower.
“血管畸形”包括一组由血管或淋巴管结构异常增生形成的病变。动静脉畸形（AVM）是高流量畸形，其特征是动脉和静脉之间直接相通，缺乏正常的毛细血管网络。AVM通常是先天性的。据报道，后天性AVM是由创伤或激素变化引起的。后天性AVM在口腔中虽然罕见，但一旦出现则具有持续性和进行性，可表现为一种致命的良性疾病。它们常伴有大量失血，不完全切除往往导致病变复发，且复发后的病变常常比原来更大。我们报告了一例罕见的后天性AVM病例，该病例通过对比增强计算机断层血管造影和组织病理学在一名65岁的职业小号吹奏者中得以诊断。
