Narrative:

As we were cleared onto the runway for takeoff the lead flight attendant entered the cockpit to inform us that a passenger claimed there was smoke at the right wing near the window. We told her that it was exhaust smoke from the APU we had just shut down, probably the result of residual de-icing fluid. We continued onto the runway and took off. We wrote the incident up and had maintenance check the APU at destination. Nothing unusual was noted. In retrospect I should have exited the runway, visually checked the wing area and APU exhaust and calmed the concerns of the passenger. Too much familiarity with this type of problem allowed me to dismiss it without proper consideration.
