Figure 5. Histopathology slides of biopsied left deltoid muscle mass. (A) Entrapped skeletal muscle fibers at the periphery of the tumor (lower half represents the skeletal muscle fibers which are splayed by the tumor cells). (B) The tumor is a hypocellular lesion composed of bland cells in a background of abundant extracellular myxoid stroma. (C) Small capillary-sized vessels are seen. Necrosis and mitotic figures are not identified. Uniform spindle-to-stellate-shaped cells with uniform oval nuclei and indistinct eosinophilic cytoplasm are noted.
