I do not see any problem if your visa is still valid and you do not stay longer than 90 days total in 6 months period. Often different Italian authorities could give you different answers :) Immigrations officers in the airports in Italy don't care much when you leave the country as long as you have anything valid you should be fine. It could be a good idea to send an email to your consulate and have a printed answer with you.
