As the GP said there are several stones commemorating polish victims in Berlin and other places. In this case the stones mark the places where the victims lived. I assume most Polish victims did not live in the territory of present day Germany. From personal experience I recall some with "eastern" names in a town that used to have a notable polish minority but I couldn't say for sure. Btw Can you recommend places to visit to learn more about their stories and history (besides the former sites of the concentration camps)?
