Vacuoles: Small, Clear, Multiple (H&E stain)  

Vacuoles: Magenta rim (GT stain)  

Vacuoles: May stain for esterase  

Vacuoles: Staining of rim on VvG Vacuoles: More common in type I fibers (ATP pH 9.4 stain)

Vacuoles: Staining of some vacuoles with acid phosphatase Abnormal internal architecture (NADH stain)

Vacuoles: Caveolin staining

Vacuoles: Caveolin; A caveolin aggregate is also present Vacuoles: Dystrophin

Vacuoles: No staining with laminin-α2 Vacuoles: Punctate staining with laminin B

From: Robert Schmidt MD
Vacuoles & Clusters: Contain cytoplasmic debris, electron dense material & myeloid bodies.
    Some clusters are encircled by a membrane
    Abnormally shaped mitochondria are located near some clusters
 
Vacuoles: Higher power view Sarcolemma: Disordered with numerous associated vacuolar structures
