question: I had a lesion removed from my left ear (superior helix) that pathology says is Matrical Carcinoma. My dermatologist has never seen this. He is researching what to do other than biopsy more tissue to get clear margins. There is little on the web about this. How concerned should I be? Other than removing it, what other follow up treatment should I consider? The Doctor said it can metastasize but thinks it was caught early. Advice?
