The term "trabecular myopathy" has been used to designate a syndrome resembling limb-girdle muscular dystrophy in which the predominant pathological feature is an abundance of lobulated or trabecular muscle fibers. However, the validity of this nosological entity has not been verified. Herein we describe a 63-year-old man with a severe, progressive myopathy who exhibited the typical pathological features of both trabecular myopathy and nemaline myopathy in association with a biclonal gammopathy. In this case, adult-onset nemaline myopathy was probably the primary disease process. The diagnostic significance of trabecular muscle fibers remains uncertain.
术语“小梁状肌病”已被用于指代一种类似于肢带型肌营养不良的综合征，其主要病理特征是存在大量分叶状或小梁状肌纤维。然而，这个疾病实体的有效性尚未得到证实。在此，我们描述一名63岁患有严重进行性肌病的男性，其表现出小梁状肌病和杆状体肌病的典型病理特征，并伴有双克隆丙种球蛋白病。在这个病例中，成人起病的杆状体肌病可能是主要的疾病过程。小梁状肌纤维的诊断意义仍不确定。
