That could be a histiocytoma which is a benign tumor that often will regress on it's own but it is difficult to be sure just by looking at some photos. Some other possibilities: an injury, an infection, a cyst, an autoimmune disorder. It is good you are taking her to the vet for an exam. They can tell you more after looking her over.
