Necrotizing fasciitis is a rare and severe bacterial infection that affects the deeper layers of skin and soft tissue. It progresses rapidly and is more common in people with compromised immune systems. The bacteria infiltrate through a minor cut or scrape and release toxins that kill surrounding tissue. Symptoms include a small, painful lump that grows quickly and turns black as the tissue dies. Aggressive treatments involving antibiotics, surgery to remove dead tissue, and skin grafts are needed to prevent severe deformities or death from this infection.

2. Features
 Rare infection of the deeper layers of skin
and subcutaneous tissues.
 Progresses quickly
 Greater risk of developing in people with
compromised immune systems (diabetes,
cancer, HIV +)
 Necrotizing-dead
 Fasciitis-fascia

3. Underlying Causes
A very severe form of necrotizing fasciitis is
caused by Streptococcus pyogenes.
 GAS bacteria
 Usually caused by bacteria infiltrating
minor cut or scrape.
 The bacteria then grow and release toxins
that kill tissue.

4. Organ Systems
 Necrotizing fasciitis affects the following
systems:
 Integumentary
 Muscle
 Immune
 Lymphatic
 Nervous

5. Prevalence
 Approximately 600 people contract
necrotizing fasciitis in the US each year.
 That equals about 1 in 453,333 people
 More males than females are affected (3
to 1)
 More prevalent in the
immunosuppressed.

6. Symptoms
 Small, red, painful lump on the skin
 Changesto a very painful bruise-like area
and grows rapidly, sometimes in less than
an hour
 The center may become black and die
 The skin may break open and ooze fluid

8. Tests
 Usually visual diagnosis
 Can also use CT scan, blood tests, and
skin tissue biopsy.

9. Treatment

10. Treatment
 Powerful I.V. antibiotics
 Surgery to drain sore and remove dead
tissue
 Donor immunoglobulins (antibodies)
 Other treatments may include:
 Skin grafts
 Amputation
 Hyperbaric Oxygen Therapy

11. Prognosis
 Depending on your overall health and
living situation, this disease will usually
cause:
 Scarring and skin deformity
 Rapid death without proper treatment

12. Conclusion
 Necrotizing Fasciitis only affects 600
people annually, so there is no need to
be worried.
 Without proper treatment, this disease
may cause severe deformities and
possibly death.
 As with all other diseases, time is a factor.
