Which local manifestation is associated with phase 2 of necrotizing fasciitis?

1. Crusty scabs

2. Patchy blisters and blue-green discoloration

3. Dry, flaking skin

4. Foul odor from the infected area

The correct answer is: Patchy blisters and blue-green discoloration

Phase 2 of necrotizing fasciitis is characterized by the rapid progression of infection and significant tissue damage. The local manifestations during this phase often include patchy blisters and discoloration of the skin, which may appear blue-green due to the presence of bacteria and the effects of tissue necrosis. The development of blisters indicates the body's response to the severe infection, as the skin begins to break down and fluid accumulates beneath the epidermis. The blue-green discoloration is typically associated with infections caused by specific bacteria, such as certain strains of Staphylococcus or Streptococcus, which can produce pigments or cause tissue ischemia and necrosis. Understanding these manifestations is crucial as they inform the urgency of medical intervention required to manage the infection and minimize tissue loss.
