I'm thinking of high profile cases, especially those involving powerful men, politicians, and clergy. This seems to be a different order of behavior than typical child abuse.
Extrafamilial offenders who abuse boys are specifically targetted by the law in a way that men who abuse girls, or men who commit incest, are not. They are more likely to get caught, more likely to end up in front of a judge and more likely to draw media attention.
This "special" category of "high profile" cases has nothing to do with the offenders themselves, but rather the response of the law and the media to those offenders. All the evidence suggests that girls are victimised at a higher rate then boys both inside and outside the family, but people implicitly take this abuse less seriously.
