Extreme dermatology--the intensive care skills of dermatologists in three case presentations of acute skin failure.

Dermatological emergencies include a number of clinical conditions usually accompanied by systemic symptoms that can lead to life-threatening complications. From the broad spectrum of life-threatening dermatoses, three cases are presented: a case of febrile ulceronecrotic Mucha-Habermann disease (FUMHD), a case of pemphigus vulgaris mimicking Stevens-Johnson syndrome (SJS), and a case of toxic epidermal necrolysis (TEN). Those cases were considered extreme, and presented to illustrate the positive outcome of timely intensive dermatological care. An interdisciplinary approach is essential in the diagnosis, treatment, management, and follow up of patients with life-threatening dermatoses.
