it should be dealing with medical stuff...

As others have commented, the most common is going to be lack of oxygen, often related to circulatory problems (such as congestive heart failure).
HOWEVER, if you're wanting something medical AND a little offbeat: be aware that use of certain metal compounds can cause a bluish or greyish coloration in the skin itself. Back in the 1930s, mercury compounds were used topically as skin whiteners and freckle removers---and some people developed significant skin discolorations as a result. I THINK that some folk nowadays using colloidial (spelling?) silver internally have had similar problems.
If you're wanting a REALLY blue tinge, just for giggles, go read _Eleven Blue Men_ by Berton Roueché. (You wouldn't believe what caused the men to be really, really, really blue....Medical detection stories, LONG before *Quincy*. If your library doesn't have a copy, Google the phrase--you might be able to find the story online. COOL reading!)

Can be caused by lack of oxygen, circulatory problems or certain heart conditions . For more info try a medical site or dictionary such as Mosby's .
