title: Great cases from the University of Pennsylvania.
abstract: 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.
