Answer

Severe myositis accompanying septic necrotizing fasciitis may be caused by a Panton-Valentine leukocidin–positive S aureus strain. [33] Immunostaining may document strong binding of the Panton-Valentine leukocidin toxin to necrotic muscle tissues.

Although necrotizing fasciitis most frequently develops after trauma that compromises skin integrity, it may rarely develop in a healthy person after minor trauma such as an isolated shoulder sprain that occurred without a break in skin barrier. [34]
