Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - This infection causes rapid necrosis and liquefaction of fascia, muscle, and tendon. Most cases involve Clostridium perfringens; Streptococcus pyogenes accounts for most of the remaining cases. Myonecrosis is classically associated with trauma (including surgery) and diabetes. There is edematous bronze or purple discoloration, flaccid bullae with watery brown nonpurulent fluid, and a foul odor. The classic presentation is pain out of proportion to physical findings. Systemic signs are also typically present and may develop rapidly into shock.
