The new deal will keep the former Chelsea defender at PSV Eindhoven until 2018.
“It is clear that we have a mutual confidence in each other,” the 24-year-old Bruma said on the club’s official website.
“This is my third season. On my arrival we expressed goals together. They are all true so far.
“We have become champions and I have become an international. With this new contract I’m showing that I’m happy here.”
