Necrotizing fasciitis is a rare, but harmful soft tissue disorder connected with microbial infections and leading to necrosis of the structural part and underlying flesh of the skin. Indications of necrotizing fasciitis go back to the 5th century BC.
Cellulitis is a bacterial infection that grows below the skin surface and can cause permanent tissue damage. It is normally caused by the bacteria Streptococcus pyogenes or Staphylococcus aureus, which commonly enters the body through a cut or other break in the skin. However, there are reported cases of cellulitis where the skin was not broken, and typically involve people who have a weak immune system or have been diagnosed with diabetes. These people are also more likely to experience serious effects from cellulitis and may even get cellulitis again.
