I claim the ornamental design for desk with leather portions, as shown and described.
FIG. 1 is a front perspective view of the desk with leather portions of the claimed design. In the drawings, leather portions of the desk are indicated by groups of intersecting lines and other portions of the desk are indicated by groups of parallel lines;
FIG. 2 is a back perspective view thereof;
FIG. 3 is a right side view thereof;
FIG. 4 is a left side view thereof;

The dot-dash broken lines represent portions of the desk that form no part of the claimed design. The short evenly spaced broken lines represent stitching.
