Descending through 4;300 feet on arrival vectors for visual approach; rwy 28R PDX; heading 030 magnetic; 210KIAS; approximately 2-4 nm SSE of town of Damascus; OR. Captain PF; First Officer PM; Clear and vis greater than 10sm. Drone came into view; spotted only by First Officer for less than 1 second; left side; 11 o'clock to 9 o'clock passed between 50 ft and 100 ft off left wing. Unable to perceive drone movement due to fast; brief pass. Drone was same altitude as aircraft when spotted. Drone was roughly size of larger DJI drone; but type/style of drone could not be determined. Appeared symmetrical laterally and longitudinally. It was bright white and highly reflective on top. No avoidance maneuvers made due to how quickly we passed it (otherwise maneuvers likely would've been made). Immediately reported to Portland approach. Flight continued without further incident. Seeing as we could not have done anything different ourselves; only suggestion is to implement TCAS on all drones; provide drone-finding radar; and/or equip aircraft with anti-drone lasers.
Air carrier flight crew had a near miss with UAS while on vectors to an approach. Flight crew reported to ATC.
