A 32-year-old woman is described as having the following characteristics of 
Emery-Dreifuss muscular dystrophy: humeroperoneal muscular atrophy and weakness, 
neck and elbow contractures with sinus bradycardia, first-degree 
atrioventricular block, and dilated cardiomyopathy. The biopsy specimen of 
skeletal muscle showed dystrophic character; a cardiac endomyocardial biopsy 
specimen showed adipose tissue infiltration and deposition of antihuman IgG. 
Emery-Dreifuss muscular dystrophy is an X-linked recessive myopathy. The patient 
had no familial background of the disease. This patient might have a sporadic 
inheritance pattern with severe cardiac involvement.
