How is Panna Cotta a true Italian dish?

Or how does the ingredients used in panna cotta make it an Italian dish?
Update: Is the cream used in Panna Cotta only available in panna cotta? Other than that the dish was invented in Italy, what else makes it Italian e.g are the ingredients used, traditional to Italy or something?
Update 2: I meant "Is the cream used in Panna Cotta only available in Italy?"
