Snapshot A 50-year-old man with a history of HIV presents to his infectious disease clinic for a rash. He reports that he stopped taking his anti-retroviral medication about 2 months ago due to gastrointestinal upset with each dose. He reports feeling well overall but reports developing a painless rash on his legs. Yesterday, he had night sweats and a low-grade fever. On physical exam, there are scattered violaceous papules and plaques on his bilateral lower extremities. Laboratory studies reveal a CD4+ count of < 200/uL. A skin biopsy is taken, and the patient is restarted on antiretrovirals and started on interferon therapy.
