If in a thickened surface squamous epithelium, one sees squamous eddies and kertain pearls and a very mild dysplasia, does the presence of squamous eddies and kertain pearls make it a SCC-in-situ? or, can the squamous eddies and kertain pearls be seen in a squamous papillom aor Seb keratosis?Thank you.
