A rapidly fluctuating rash in a stuporous patient

There is a range of skin changes that are transient in nature, from urticaria to vasomotor disturbances such as Raynaud phenomenon and flushing. However, rapidly fluctuating lesions that appear then disappear in a matter of seconds to a minute are rarely observed and are not well documented in the dermatologic literature. Herein, we describe an unresponsive young man with rapidly fluctuating patches of erythema in whom the neurologic and cutaneous symptoms improved following treatment for benzodiazepine withdrawal–induced catatonia (BWC).
