Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor. It may be necessary to remove the lesion and submit the tissue to a pathologist for evaluation.

Evaluation: The only way to be sure and give you an appropriate diagnosis is by an in person facial exam. Please consult with your physician. Hope this helps.
