Yup. If you failed to remove that one offending page, you'd get a very long and rigorous appeal process. They have a special team that only does this and they are quite unforgiving. They not only look at the adult content of your site but also other violations like copyrights, forum spams, etc. so the likelihood of your site reinstated is slim to none.
But you know what's disturbing? Had you removed the offending page in the first place, your violation would have been resolved because the robot is not as strict. Just browse other sites that display Adsense, you'll find that they're in violation worst than yours.
For now, I'd suggest to clean your site again -- remove images with skin (think conservative grandma viewing your site) and file a second appeal.
