Two things

1) You're using the function wrong, it should be (similarly for the mouseleave function)
Code: [Select]
jQuery(document.body).on("mouseenter", "#ultimecomunicazioni", function() {
        jQuery('<span id="ultimecomunicazioni_appear" style="font-weight:normal;margin-left:5px">(<a style="color:grey" href="//google.it">tutte</a>)</span>').appendTo(jQuery(this));
 });

2) You're delegating events to an ID, that's pointless since you're only supposed to have one element in the DOM with the same ID. You might as well use bind after document.load
The way it's meant to be

Yup, this works now ;)

Uhm, anyway the documentation says:
As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements.

What about this?
Code: [Select]
$(document).on("mouseenter mouseleave", "#ultimecomunicazioni" , function(e) {
    if(e.type === 'mouseenter'){
        $(this).append('<span id="ultimecomunicazioni_appear" style="font-weight:normal;margin-left:5px">(<a style="color:grey" href="blahblah/">tutte</a>)</span>');
    } else {
        $('#ultimecomunicazioni_appear').remove();
    }
});
