Use bwdist() to locate pixels within 100px of your Pixel-of-Interest ( bwdist even provides fancy alternate methods of doing this!). Then either mask this off or require that the CC.PixelIdxList (output from bwconncomp) values intersect with one of the pixels in your region-of-interest to include that object in your analysis
