Well if you are respawning (reinforcing) then the aforementioned rule applies: place it in the nearest empty space to an entrance tile space where it will fit (if there is no room on the entrance tile to fit it properly.)
As for the case of the entrance tile being empty or at least having enough space to fit the monster: as far as I'm concerned the RAW do not explicitly require the entire base to be on the tile (or any assigned tile during map setup for that matter.) However, I emailed FFG and their reply was that it should be entirely on the intended tile if possible.
Awesome, thanks for clearing it up.
