FIGURES AND TABLES LEGEND
Figure1. Histology
- H&E-stained section showing cells with a mesenchymal appearance set
in a loose background stroma, and showing with variable (in this
focus, relatively little) skeletal muscle differentiation.
- Desmin immunohistochemistry, showing diffuse cytoplasmic expression in
neoplastic cells
- Myogenin immunohistochemistry, showing nuclear expression in fewer
than 50% of neoplastic cells
- MyoD1 immunohistochemistry, showing nuclear expression in
approximately 50% of neoplastic cells
