Unstyling custom fields

I’ve searched the docs and forum, but may not be looking for the right thing…

I want to display the custom field unstyled – in other words, I don’t want to display it as a list. Nor do I want to display the name of the field or the colon.

Basically, I have a page that I want to display in the sidebar as Corporate, but on the page as Corporate Services. Because pages don’t have descriptions, or summaries, all I can think of to use is using the custom field to add “Services” to the parent pages (the child pages wouldn’t need the word “Services” so I haven’t hardcoded it into the page template).

Is there another way to do this. It’s very much a hack.
