Hello,
Thanks for posting your query at DoctorSpring. From your question it seems you are looking for a possible diagnosis and next course of action.
From the pictures, it seems to be a lesion that we call Erythroplakia. It could be a pre-malignant condition and hence needs to be examined by your doctor.
I would recommend that you meet your doctor as soon as possible for examination and evaluation.
Please let me know if you have any further queries.
My apologies for the exceptional delay with the reply.
Take care
Regards
