Lots Of Comments, But No Comments. Where Are They? How Do I Delete?

I just noticed something I find a bit scary in the backend of one of my shopping WP sites. In the comments area it shows 14,121 comments!?, However, none of these entries shows up anywhere the list.
Maybe paranoia, but that looks really bad to me!
Can anyone gives me a "what gives" and a recommendation on deleting all of these so called comments?
Thanks!
