In a routine dissection of the axillary fossa, a muscle originating from the coracoid process of the scapula and extending to the long head of triceps brachii muscle was observed. The mentioned muscle was adhering to both the triceps brachii muscle and the tendinous part of the latissimus dorsi muscle. This anatomical variation is referred to as axillary arch (Langer's muscle or axillopectoral muscle). The muscle mass was measured 9.6 cm in length and 1.4 cm in width. The accessory muscle can be a reason of an axillary mass and can exert pressure on the neighboring neurovascular bundle or lymph routes; thus, exposing a wide range of symptoms. Therefore, variations of this area should be kept in mind in surgical interventions.
在腋窝的常规解剖中，观察到一块肌肉，它起自肩胛骨的喙突，延伸至肱三头肌长头。上述肌肉附着于肱三头肌和背阔肌的腱性部分。这种解剖变异被称为腋弓（兰格肌或腋胸肌）。该肌肉块长度测量为9.6厘米，宽度为1.4厘米。这块副肌可能是腋窝肿物的一个原因，并且可能对邻近的神经血管束或淋巴路径施加压力；因此，会出现各种各样的症状。所以，在外科手术干预中应牢记该区域的变异情况。
