Reportability--Skin: Is this case not reportable if the intranasal polyp is covered with cutaneous epithelium (essentially skin) or, is it reportable as a primary intranasal basal cell carcinoma? I have found one article regarding primary intranasal basal cells, which are described as being "very rare". But, I am not sure whether, in those cases, cutaneous epithelium was found.
