About Permesso di Soggiorno

Requirements for immigrants leaving Italy temporarily

Foreigners awaiting renewal of their residence permits can leave and re-enter Italy if they hold:

the receipt issued by Italian Post offices (Poste Italiane S.p.A) certifying the submission of the application for renewal of their residence permit or EC residence permit for long-term residents;
the expired residence permit;
their passport or other equivalent travel document .

The same facilitated procedure is granted to foreigners who have submitted their application for their first residence permits for employment, self-employment, or family reunification, provided that:

they leave and re-enter Italy through any Italian external border crossing point (cicular letter 11th March 2009);

they show their passport or other equivalent travel document, along with the entry visa specifying the reasons of their stay (employment, self-employment, or family reunification ) and the receipt issued by Italian Post offices (Poste Italiane S.p.A.);

As addition, if you provide these requirements, go by flight and use same port.

Thank you for the reply.
Although this mentions the foreigners who have submitted their application for their first residence permits for employment, self-employment, or family reunification, it does not say about STUDENT. 
What do you think about this?

If I were you, I wouldn't go.

Hello,

I I don't know if this information helps you but I'm also here with a student visa and I traveled to Netherland after 4 months of being here, this was also before my questura appointment and I had no problem at all! I traveled with my passport and the document showing that I had a questura appointment for my first Permesso. I don't know the rules about this I'm only talking about my personal experience, hope it helps.
