title: Concentric laminated bodies in muscle pathology.
abstract: Concentric laminated bodies are described in five cases (one case previously reported and four new ones) of various muscle diseases. A general review of previous reports on these structures is made. They appear to be unspecific bodies generally noticed in abnormal skeletal muscle in various disorders; nevertheless they were found in normal muscle fibres of the mothers of children affected by myopathy. They have a complex filamentous structure. According to the authors, their myofilamentous nature is uncertain but seems more probable than a mitochondrial or lipidic one.
