Ulcerated describes a part of the body that has broken open into an ulcer — an open sore that stays open. An ulcerated leg has a raw wound on it; an ulcerated stomach has sores in its lining; an ulcerated tooth socket is one where the gum has broken down. It is an adjective made from the verb 'ulcerate', and it is by far the commonest of that word family in real medical speech, because doctors describe what they are looking at right now: 'the wound is ulcerated'. It works both before a noun (an ulcerated leg) and after 'be' or 'become' (the area became ulcerated). Two things to feel about it. First, it means the breaking-open has already happened — it is a finished state, not a warning. Second, it carries a sense of long-standing trouble; ulcerated wounds are the ones that have been there a while, not a fresh cut. Outside medicine you will hardly ever hear it, though writers sometimes use it about a place or a situation to mean something sore and festering that will not close over.
