A 62 year old male presents to the urgent care clinic with complaints of worsening nodules to his neck that have now appeared to his face. He states this started a year ago, but has gotten worse. On exam you note he is a white male with fair complected skin. When you ask about medical and social history, he reports he has hypertension and GERD. States he works as a landscaper.  On physical exam you note nodules to the neck that are waxy and pearly in appearance.  You refer the patient to an outpatient dermatology clinic for biopsy, because you are concern for which condition?
