In a recent Physical Review Letter, Kondo and Morimatsu present a QCD sumrule calculation of nucleon-nucleon scattering lengths. They also relate theempirical scattering lengths to the nucleon mass shift in nuclear matter tocast doubt on the "linear density approximation." In this Comment, we point outflaws in both parts of their analysis and draw very different conclusions.Comment: 4 pages in RevTeX, OSU-0901/UTHEP-26
