In this visual world, dermatologists and often physicians may not "know" what they see. Compared with the dermatologists of bygone eras, most of us are less able to describe lesions, arrangements, and relationships. For example, many modern dermatologists speak of "erythematosus papular lesions" rather than "pink, round, 5-mm slope-shouldered papules." With this carelessness and an unshakable belief that our eyes alone can diagnose, we risk becoming careless dermatologists by making diagnoses from viewing patients across the room and telling each other we recently had a patient "exactly like this" (no 2 patients are exactly alike if we look closely).
