In Italy there's a bunch of things called "pizza" which are not round flat bread.
Consider the pizza di Pasqua (dough with liquor, chocolate, cheese, +20cm tall), pizza alla pala (1.5m long), pizza sbattuta (sponge cake), pizza in teglia (rectangular and cut in square slices), and many more.
Could be related to pita, and I would not argue every culture on earth made flat round dough and put stuff on it, but it's a very large family.
