On Galuna Island Gray was run through the liver by a sword and he had a lengthly fist-fight before he stopped the bleeding by freezing over the wound.

In the Tower of Heaven arc Jellal survived having his stomach sliced open and fought an intensive battle afterwards without ever adressing the wound.

I guess the example of Makarov getting a hole through his body doesn't really cound due to god mode cheat Tenrou Island's magic.

And I'm sure if you look through the manga carefully, you'll find several other similar examples. Who cares if his left lung was penetrated? He still has a second one that works just fine! :P
