A 42-year-old man, known to have human immunodeficiency virus (HIV), attends his regular clinic appointment. He has missed an earlier appointment and is poorly compliant with his antiretroviral therapy, which he puts down to his busy work schedule. He has recently noticed blotches on his nose. His partner reports that the patient also has similar lesions on his back.
On examination, you note several red-purple papules across the patient’s back and face.
