Please first try running the uninstaller in Applications/Utilities/Adobe Installers. Once that is done you can utilize the clean up tool by following the directions at CS Cleaner Tool for installation problems | CCM, CS6, CS5.5, CS5, CS4, CS3 - http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.html. This should remove any additional components.
In regards to uninstalling on Mac. Many applications are able to utilize the package feature to contain all of their components. Do to the shared components between Adobe applications and their multi-platform nature we utilize an uninstaller. This is because we do not contain all of the files required for the application within the package for the application itself.
