title: [A pedigree of autosomal dominant limb-girdle myopathy with rimmed vacuole formation].
abstract: We describe a kindred with autosomal dominant myopathy with preferential proximal limb muscle involvement. This disorder is characterized clinically by early adult onset, slow progression, normal life expectancy, weakness and atrophy of proximal limb muscles, especially in the lower limbs. Laboratory examinations showed myopathic changes mixed with neuropathic components on needle electromyography, slight elevation of serum creatine kinase, and absent cardiac involvement. In biopsied muscle findings of two patients, the presence of rimmed vacuoles was the most striking finding to explain muscle degeneration, though a few necrotic fibers were present. The pathologic and clinical findings in the present family are almost similar to those seen in "adult-onset autosomal dominant limb-girdle muscular dystrophy" reported by Chutkow et al.
