A set of monozygotic twins affected with unilateral shoulder girdle muscle aplasia is reported. One twin showed Poland-like aplasia of the pectoralis but without the ipsilateral dysmelia, the other aplasia of dorsal spinothoracic muscles. The controversy about exogenous or genetic causes of the Poland anomaly and the whole spectrum of shoulder myaplasia may be solved assuming a multifactorial origin. The striking sex distribution and the continuous range of symptoms observed are in keeping with this hypothesis.
报道了一组患单侧肩胛带肌肉发育不全的单卵双胞胎。其中一个双胞胎表现出类似波兰综合征的胸肌发育不全，但无同侧肢体发育异常，另一个则是背侧胸段肌肉发育不全。关于波兰综合征及整个肩胛肌发育不全谱系的外源性或遗传病因的争议，若假设其起源为多因素，则可能得到解决。所观察到的显著性别分布及症状的连续范围与这一假说相符。
