Atalanta suffered a shock home defeat and made costly defensive errors, as Sampdoria ended their run of three consecutive losses.
The hosts had been on a roll of three wins in four games, keeping three clean sheets, but this could be a crucial result in the race for Europa League spots.
Rafael Toloi was at fault for the opener, his howler allowing Gianluca Caprari to score, then made up for it by netting the equaliser from a knocked-down free kick.
