Well, I got the results of my biopsy, it was done at UCLA Oral Pathology Lab. The CLINICAL DIAGNOSIS: ?

So they don't know what it is either, but there is no evidence of malignancy.

"The microscopic findings have some features of, but not diagnostic for lichen planus"

I was given a prescription for another steroid gel that is to sooth the lesion. I am hoping it does not continue to grow, and plan on watching it closely for any changes.
Thanks for all of your support and help. Mary
