Get some rubber or wear a latex glove and putting pressure on the surface try and rotate it back with lens release pin depressed at the same time. It should come out with some elbow grease applied

This thread might help, but it involves some "surgery":

First try to hold the lens release button on camera, then move adapter to where it should come out and wiggle it out. Don't push down on the adapter, only spin it

Removing the lens mount will be difficult since the flange covers the screws. You should be able to grip the ring on the knurled part while wearing a rubber glove and twisting it off while depressing the lens release button. Try it with pushing the ring towards the body. Try it while pushing the ring towards the body. You could probably put your thumb on the inside of the ring but be careful of the mirror, focusing screen and power zoom contacts.

More extreme options would be to cover over the opening and drill a couple of holes in the flange or inner flange so you can turn the adapter with a lens spanner wrench. I would use a drill press so you can accurately control the depth of the drill holes.

Yes, use rubber gloves and no, don't apply downward pressure. That style adapter has no retaining spring and should turn turn out properly with the release button depressed.

Putting a finger on the inside surface will definitely help, though I am still dubious about putting downward pressure on the adapter.

Cutting the adapter out with a Dremel too is a drastic last resort and requires a steady hand and care to keep the metal shards out of the body.

Thanks for clarifying - obviously by saying putting pressure I meant to ensure the grip is good and friction will do the rest while turning. SO the pressure needs to be applied, but very balanced just so the rubber wont slip.
