She was in her usual state of health until about 3 months ago when she started to develop some painfully itchy spots across her scalp. Since that time these spots have lost hair and scarred, with new spots continuing to form. On further questioning, she shares that, for the last couple of years, she has generally felt poorly, specifically noting intermittent fevers, muscle and joint pains, and fatigue. On physical exam, she has several erythematous and scaly plaques across her scalp. These areas have no hair growth, but some do demonstrate hyperpigmentation. Which of the following is the most likely diagnosis?? A: Alopecia areata, B: Discoid lupus erythematosus DLE, C: Secondary syphilis, D: Tinea capitis, E: Trichotillomania,  <response>: Based on the description of painful hair loss in patches across the scalp that have scarred and lost hair, along with a history of fevers, muscle and joint pain, and fatigue, the most likely diagnosis is discoid lupus erythematosus DLE. Alopecia areata presents with non-scarring hair loss without associated systemic symptoms. Secondary syphilis may cause hair loss but would not lead to scarring. Tinea capitis may be associated with hair loss but is a fungal infection that would not cause systemic symptoms. Trichotillomania is a psychiatric condition causing hair loss from compulsive hair pulling, which does not fit with the scarring and systemic symptoms described.B: Discoid lupus erythematosus DLE
