The two-proton stability in even-even nuclei around the doubly magic ${}_{}{}^{100}{}_{}{}^{}\mathrm{Sn}$ is examined by the self-consistent Skyrme-Hartree-Fock-Bogoliubov theory. According to our analysis, the nuclei ${}_{}{}^{98}{}_{}{}^{}\mathrm{Sn}$ and ${}_{}{}^{106}{}_{}{}^{}\mathrm{Te}$ are stable to two-proton decay while ${}_{}{}^{96}{}_{}{}^{}\mathrm{Sn}$ and ${}_{}{}^{104}{}_{}{}^{}\mathrm{Te}$ lie beyond the two-proton drip line.
