Intramuscular hemangiomas are rare tumors. Their occurrence in the head and neck region is even more unusual. The first reported case involving the orbicularis oris muscle is presented. The histologic classification is that of the mixed-vessel type, which occurs in the head and neck region only 5 percent of the time. Included is a review of the literature, with a discussion of the current philosophy of etiology, diagnosis, and treatment. Knowledge of this type of tumor is important to the oral and maxillofacial surgeon who evaluates mass lesions.
肌内血管瘤是罕见的肿瘤。它们发生于头颈部区域则更为少见。本文报告首例累及口轮匝肌的病例。组织学分类为混合血管型，该型仅5%发生于头颈部区域。文中包括文献综述，并讨论了当前关于病因、诊断和治疗的理念。了解这类肿瘤对于评估肿块病变的口腔颌面外科医生很重要。
