Certain optical illusions can generate square circles as well, plus its possible for them to exist on smaller scales (the sub-atomic and below) were the laws of physics become looser as shapes that exist on that scale can't exist on higher scales without changing the laws of distance and space.

So while it may seem like a contradiction to us, in the proper context and setting its more unlikely then impossible.
