You are seeing a new patient, a rather distinguished fellow named Mr. Bach Hertz. He is a 78 year old musician, with metastatic prostate cancer to his vertebra. His bone pain is being treated with radiation therapy and zoledronic acid. Today, the nature of his visit is a new scary looking mole he found on his back. You take a quick peak, and are confident it is nothing but a lonely seborrheic keratosis. Reassured, your patient goes to leave, but just as he is leaving says “Hey Doc, I haven’t been to a dentist in a while but feel like i’ve had some tooth or jaw pain recently”. An alarm bell go off. Why?
