limb-girdle

Objective To study the clinic and pathological features of 4 cases of lipid storage myopathy ( LSM) and differential diagnosis with Duchenne/ Becker muscular dystrophy 、 limb-girdle muscular dystrophies and polymyositis.

目的通过分析4例被误诊的脂质沉积性肌病的临床及病理特点，探讨脂质沉积性肌病被误诊的原因及与假肥大型肌营养不良、肢带型肌营养不良及多发性肌炎的鉴别诊断。

The limb-girdle muscular dystrophies are divided into two types according to inheritance pattern, type 1 is autosomal dominant and type 2 is autosomal recessive.

目前根据遗传方式分为1型（常染色体显性）和2型（常染色体隐性），每一型根据不同基因缺陷又分为许多亚型。

Two patients were diagnosed as facioscapulohumeral muscular dystrophy, one as limb-girdle muscular dystrophy and the others' etiology were unknown.

其中2例临床诊断为面肩肱型肌营养不良，1例免疫组化染色证实为肢带型肌营养不良，余均未发现明确病因。
