CASE #1
CASE #2
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.
A 15-month-old boy with a 2-day history of worsening rash presents to the emergency department with his parents. He recently was diagnosed with otitis media by his primary care provider, for which he was given amoxicillin. His parents report that the rash began about a week after the boy started taking amoxicillin and has been progressively worsening. No prescription or over-the-counter treatments have been tried for the rash, and the patient has no other significant medical history. On examination, the patient has well-demarcated erythematous plaques with central areas of violaceous discoloration on the face, chest, back, and upper and lower extremities.
