Case 1

A 12-year-old boy presents to the dermatology clinic with a reddish-brown rash. His mother reports that the rash started as reddish-brown spots and has become very itchy, often keeping her son up at night. She is concerned that it may be varicella zoster virus infection. Physical examination reveals scaly, erythematous macules with areas of ulceration along the anterior trunk, arms, legs, and elbows. Two weeks ago, the boy missed school due to a “sore throat” and mild flu-like symptoms, but his mother reports that she did not take her son to the doctor or seek treatment.
