Fig 1 A, Clinical and dermoscopic images of the lesion. A 10-mm, irregularly pigmented papule with a grey-whitish depressed central area. B, Dermoscopic image of the lesion shows a central white scar–like patch surrounded by peripheral reticular depigmentation. Dotted and nonspecific vascular structures are also observed in the central area.

Fig 2 Histopathologic images of the lesion. A, Panoramic view reveals a symmetric lesion with a well differentiated central area. B, The margins of the lesion show a junctional proliferation of pigmented melanocytes arranged in confluent nests with focal pagetoid spread of melanocytes limited to the lower half of the epidermis. C, The central area shows epidermal atrophy, hypogranulosis, and a dermoepidermal cleft–like reaction with a mononuclear infiltrate in the papillary dermis (Hematoxylin-eosin stain.)
