Star-shaped dusty cores and ultrastructural finding diagram. Longitudinal section of star-like shaped dusty core by EM (a). Three-dimensional representation of dusty cores inside muscle fibre (b,1). Superficial slides showing small areas of disorganization corresponding to the peripheral-side of dusty core (b,2), leading to a possible misdiagnosis with minicores. Deeper analysis revealing the real size of disorganization (b,3)
