Case 1
A 50-year-old man presents to the dermatology clinic with a 1-week history of an itchy rash. He has tried hydrocortisone cream on the rash, which has helped relieve the itching. His wife, who has been helping to apply the steroid cream, noticed that the lesions seem to come and go and have moved to different locations on the patient’s back. The patient takes medications for hypertension and hyperlipidemia but denies starting any new medications recently. On examination, there are several well-demarcated erythematous plaques with central pallor on the lower back, buttocks, and ankles, with nearby heme-crusted excoriations.
