Lewandowski's former Borussia Dortmund teammate Piszczek was also in superlative form in 2015/16, with two goals and six assists in all competitions as Die Schwarzgelben finished as runners up to Bayern in the Bundesliga and the DFB Cup.
BVB-owned Jakub Blaszczykowski is also in the squad. The winger spent last season on loan at ACF Fiorentina, helping the team into next season's UEFA Europa League group stages with a fifth-place finish in Italy's Serie A.
Poland are in Group C alongside Germany, Ukraine and Northern Ireland. They kick off their finals campaign against the Northern Irish at the Stade de Nice on 12 June.
