71yo has had a L ear lesion before, has “gone away” and now is back. Hard, verrucous, the whole mass seems to be able to glide and not adherent to underlying cartilage, feels like a cutaneous-horn that’s gotten out of control. Has had a previous biopsy as per report that was “benign”, we’re awaiting that path report. No cervical Lymphadenopathy First thought is SCC but since I’ve never seen anything quite that large and not ulcerated like an SCC. What are your differentials?
