The following pictures are not for the squeamish.

This baby was circumcised "without incident" using a Plastibell^TM device when he was six days old. Two days later, his penis swelled up and blistered, and he became feverish. He was given antibiotics. Two days after that, his scrotum became involved and he was provisionally diagnosed with necrotising fasciitis (Fournier's gangrene or "galloping gangrene", a disease that caused a scare in the UK a few years ago). The circumcision wound was covered with yellowish granulation tissue. He was operated on to remove the dead tissue, including his scrotum, penile skin and lower abdominal wall:

He was given high-pressure oxygen, and two weeks later, skin grafts. The case was written up in Online Pediatric Urology, April 1996. You can find full details at http://www.infocirc.org/fourn.htm

This consequence of circumcision is rare, but circumcision is very common, and since it is unnecessary, so are horrors like this.
