Necrotizing fasciitis of the perineum is an uncommon, potentially fatal bacterial illness around your rectum and genitals. It is a severe infection that demands immediate medical attention. When your perineum is swollen, sensitive, or red, and you have a temperature of at least 100.4 degrees Fahrenheit or feel poorly, head to the emergency room immediately.
In addition, the soft tissues of your penis and scrotum are affected by necrotizing fasciitis of the perineum. In extreme situations, the bacterial infection spreads to the chest, stomach, and thighs, damaging the arteries, nerves, and muscles. Necrotizing fasciitis of the perineum is a potentially fatal condition. However, this condition is extremely rare, and preventative measures and treatments are available.
