Abstract: We show that sets of $n-p+\alpha (p-1)$ Hausdorff measure zero are removable for $\alpha $-Hölder continuous solutions to quasilinear elliptic equations similar to the $p$-Laplacian. The result is optimal. We also treat larger sets in terms of a growth condition. In particular, our results apply to quasiregular mappings.
