We present the generalization of the two-dimensional quantum scattering formalism to systems with Rashba spin-orbit coupling. Using symmetry considerations, we show that the differential scattering cross section depends on the spin state of the incident electron, and skew scattering may arise even for central spin-independent scattering potentials. The skew scattering effect is demonstrated by exact results of a simple hard wall impurity model. The magnitude of the effect for short-range impurities is estimated using the first Born approximation. The exact formalism we present can serve as a foundation for further theoretical investigations.
