title: Clinically unsuspected inclusion body myositis.
abstract: We describe a patient with inclusion body myositis presenting as chronic, therapy resistant polymyositis. Our report highlights the slow evolution of inclusion body myositis in some patients, and emphasizes the diagnostic importance of examining one or more muscle biopsy specimens by both frozen section and electron microscopy.
