The dermoscopic variability of Degos disease at different stages of progression

A 34-year-old woman presented with an 8-month standing eruption disseminated on the trunk and anterior upper limbs. Following their initial appearance, the skin lesions were described to occur in crops. On clinical examination, lesions of recent onset were small, dome-shaped, pale-red papules surrounded by an erythematous halo (Figure 1a), while papules of longer duration displayed a central ulceration covered by a yellowish crust and were surrounded by a whitish rim (Figure 2a). Finally, porcelain-white scars with a reddish or hyperpigmented halo were noted on the site of healed lesions.
