In 2018, Partyka et al. established several equivalent conditions for a sense-preserving locally injective harmonic mapping f = h + g ¯ in the unit disk D with convex holomorphic part h to be quasiconformal in terms of the relationships of two-point distortion of h , g , and f . In this study, we first generalize the above result to the case of pluriharmonic mappings f A = h + A g ¯ , where h is a convex mapping in the unit ball B n and A ∈ L ℂ n , ℂ n with A = 1 . Then, we establish a relationship of two-point distortion property between f and f A .
