Langer's arch is the best-known anatomic variant of definite surgical implication in the region of the axilla. This rare anomaly is a muscular slip extending from the latissimus dorsi (LD) muscle to the tendons, muscles or fasciae around the superior part of the humerus. In this report, we present a rare case of left axillary arch. During modified radical mastectomy for breast cancer, we encountered an abnormal muscle slip crossing the axilla from the LD muscle to the posterior surface of the pectoralis major muscle anterior to the neurovascular structures. Preoperative knowledge is essential to identify such unusual anomaly and avoid potential complications both intra- and postoperatively.
朗格弓是腋窝区域具有明确手术意义的最著名解剖变异。这种罕见的异常是一条肌肉束，从背阔肌延伸至肱骨上部周围的肌腱、肌肉或筋膜。在本报告中，我们呈现了一例罕见的左侧腋弓病例。在乳腺癌改良根治术中，我们遇到一条异常的肌肉束，它从背阔肌穿过腋窝，到达神经血管结构前方的胸大肌后表面。术前了解对于识别这种不寻常的异常并避免术中及术后的潜在并发症至关重要。
