A 55-year-old woman presents to the dermatology clinic with a long history of a rash that occurred during the spring and summer months over her face and scalp. Over the past few years the affected area became more extensive, the skin became scarred and she noticed her hair did not grow back. She wears a hair weave to cover the area. More recently, however, she has developed new lesions over her cheeks and is worried about scarring. She is otherwise well.
