Correct answer: B — Ulerythema ophryogenes (keratosis pilaris atrophicans faciei variant)

The best answer is “Ulerythema ophryogenes (keratosis pilaris atrophicans faciei variant)”. The diagnosis follows the defining morphology, distribution, histopathology and time course; management changes when red flags, scarring, systemic disease or malignancy risk are present. The alternatives “Eyebrow psoriasis, after clinicopathological correlation”, “Seborrhoeic dermatitis, after specialist assessment”, “Alopecia areata of eyebrows, when the full phenotype supports it”, “Frontal fibrosing alopecia, within an appropriate UK pathway” are clinically adjacent possibilities, but they do not fit the defining morphology, distribution, histopathology, risk signal or management sequence in this stem.
