title: Proximal muscle weakness in children.
abstract: In as many as half of the children referred to a muscle disease clinic, the original diagnosis is ultimately changed. Five cases histories are reviewed here in which Duchenne muscular dystrophy had been mistakenly diagnosed 3 to 12 years previously and the correct diagnosis was made only after repeat muscle biopsy or biopsy review. Four boys had diseases with a much better prognosis, and one boy did not have a muscle disease at all.
