White fibrous papulosis of the neck (WFPN) is a rare entity that was first described by Shimizu et al. in 1985 in Japan. Clinically, it presents as asymptomatic, rarely pruritic white, ivory, or yellow papules with a diameter of 2–3 mm. These papulose eruptions are firm, non-follicular, and have a smooth surface. Most often, the sides and back of the neck are affected in elderly people, but lesions may also spread across the upper part of the trunk [1].

Rare observations in the literature have focused on the interest of dermoscopy in WFPN. Dermoscopic signs are clearly circumscribed, homogeneous white areas, including dotted or short, thin vessels, without follicular involvement. Peripheral pigmentation can be seen but fails to form a pigment network [2].

The lesions shown in (Figs. 1a and 1b) were located on the necks of 67-year-old women. Dermoscopy revealed white or yellow, homogeneous, circumscribed areas without follicular involvement (Figs. 1c and 1d). The diagnosis of WFPN was confirmed histologically.
