cuterie ... erotica

(Cuterie to erotica drops the u and one e, and adds an o and an a. Are two complete letter-changes allowed?)

Nope, only one letter at a time, dropped, changed, or added. It's easy to make an error, though, especially if you're using an anagram generator. You see a really cool word in the list and don't always check the letters.
