Juve looked on course to remain clear at the summit, as they went 1-0 up at the Juventus Stadium courtesy of Claudio Marchisio's goal after just nine-minutes.
Juan Cuadrado was then sent-off for Lecce on the hour and that looked to be it for the side who are third-from-bottom.
But with five-minutes left, Lecce grabbed the unlikeliest of points as substitute Andrea Bertolacci scored.
AC Milan took full advantage of the slip-up as they beat Atalanta 2-0 at the San Siro.
A goal in each half from Sulley Muntari and Robinho did the damage for Massimiliano Allegri's men.
Udinese are now favourites for the final Champions League place as they went two points clear in fourth after 1-0 win at bottom-of-the-table Cesena.
The winner came just four minutes in with Diego Fabbrini scoring.

Things started well for Inter at the Ennio Tardini as Wesley Sneijder scoring after 13-minutes.
But Parma took control in the second-half and were ahead within ten-minutes of the re-start thanks to goals from Fernando Marques and Sebastian Giovinco.
The win was sealed by former Inter man Jonathan Biabiany with seven-minutes left.

However, the talking point from this game will be the scenes which saw coach Delio Rossi fighting with Adem Ljajic after he was substituted on the half-hour.
