description: We report the study of $B^{+} \rightarrow p\bar{\Lambda} K^+ K^-$ and $B^{+} \rightarrow \bar{p}\Lambda K^+ K^+$ using a $772 \times 10^6$ $B\bar{B}$ pair data sample recorded on the $\Upsilon({\rm 4S})$ resonance with the Belle detector at KEKB. These include the observations of decay modes with the corresponding branching fractions $\mathcal{B}$($B^{+} \rightarrow p\bar{\Lambda} K^+ K^-$ ) $=$ $(4.22^{+0.45}_{-0.44}\pm 0.51)\times10^{-6}$, $\mathcal{B}$($B^{+} \rightarrow \bar{p}\Lambda K^+ K^+$) $=$ $(3.81^{+0.39}_{-0.37} \pm 0.45)\times 10^{-6}$, $\mathcal{B}$($\eta_c \rightarrow p \bar{\Lambda} K^-$) $=$ $(2.9^{+0.4}_{-0.3}\pm 0.4)\times10^{-3}$ and $\mathcal{B}$($B^{+} \rightarrow p\bar{\Lambda} \phi$) $=$ $(0.818 \pm 0.215 \pm 0.078)\times10^{-6}$, where $\mathcal{B}$ denotes the decay branching fraction and the intermediate resonance decays are excluded in the four-body decay measurements.
