Great Cases from the University of Pennsylvania

New skin diseases are reported yearly. Some well‐known conditions may develop unusual manifestations. Other cutaneous findings are simply rare. While patients with such diseases represent only a small fraction of our practice they are an important subset of our experience. Many of these diseases are treatable, pinpoint the discovery of internal disease, or simply allow for a diagnosis and prognosis to be given to a concerned patient who had previously escaped classification. Such cases expand our knowledge and provide excitement to our day. Several patients from whom I have learned the most in the last few years are detailed for your enjoyment.
