umbraco tried this to match it using this xpath query'/root/node/node [@urlName = "breaking_news_2010"]/node [@urlName = "10"]/node [@urlName = "evolution-of-nevi-during-treatment-with-natalizumab"]')
This page can be replaced with a custom 404 page by adding the id of the umbraco document to show as 404 page in the /config/umbracoSettings.config file. Just add the id to the '/settings/content/errors/error404' element.
For more information, visit information about custom 404 on the umbraco website.
This page is intentionally left ugly ;-)
