OBJECTIVE
The study adds important information regarding the descriptive anatomy of a very rarely reported unilateral chondrocoracoideus muscle (of Wood). Additionally it highlights the concomitant muscular and neural alterations.
CASE REPORT
The current case presents the occurrence of a chondrocoracoideus muscle situated left-sided, as an extension of the abdominal portion of the pectoralis major muscle (PM). The chondrocoracoideus coexisted with a contralateral atypical PM, partially blended with the clavicular fibers of the deltoid muscle. There was an accessory head of the biceps brachii while the palmaris longus was absent on the right side of a 78-year-old Greek male cadaver.
CONCLUSION
The above mentioned muscular abnormalities are shown as disturbances of embryological pectoral muscle development, and their documentation is essential in order to increase awareness among clinicians of their potential impact on the diagnosis and treatment of several pathologies.
目的
本研究补充了关于一种极为罕见的单侧（伍德氏）喙突软骨肌描述性解剖的重要信息。此外，它还突出了伴随的肌肉和神经改变。
病例报告
本病例呈现了左侧存在喙突软骨肌的情况，该肌肉是胸大肌腹部部分的延伸。喙突软骨肌与对侧非典型胸大肌并存，部分与三角肌锁骨部纤维融合。在一名78岁希腊男性尸体的右侧，肱二头肌有一个副头，同时掌长肌缺失。
结论
上述肌肉异常表现为胚胎期胸肌发育的紊乱，对其进行记录至关重要，以便提高临床医生对其可能对多种病症诊断和治疗产生影响的认识。
