الجواب الصحيح هو a

This patient has necrotizing fasciitis. It is a rapidly progressive bacterial infection that spreads along fascial planes. It may follow trauma, but this will not always be present in the history. Crepitus is often appreciated, indicating subcutaneous air.

Treatment includes
starting IV antibiotics immediately,
early and aggressive surgical debridement,
and tetanus prophylaxis.

It is classically caused by group A Streptococcus, but other etiologic organisms include Clostridium perfringens and Bacteroides fragilis (it is also often polymicrobial). Although Staphylococci are skin flora, they are not typically implicated in necrotizing fasciitis. Mycoplasma pneumoniae and Moraxella catarrhalis are causes of community-acquired pneumonia and do not cause necrotizing fasciitis

Because Staphylococcus aureus can cause scalded skin syndrome
scalded skin syn occur in childeren and neonates
in this syndrome a s.aureus strain which produce exfoliative toxin A & B establishes a localized infection and release a diffusible toxin that exert distant effects.
it usually affects neonates with local infection of the recently severed umbilicus ot older children with skin infections
clinically it causs cleavage of the middle epidermis with fine sheets lf the skin peeling off to reveal moist red skin beneath . healing is rapid and mortality low.
