Lichen sclerosus is an uncommon inflammatory dermatosis with preferential involvement of the urogenital region. The extragenital involvement is uncommon and is characterized by small rounded macules or papules, pearly white in color.
The coexistence of lichen sclerosus and scleroderma plaques in most cases with extragenital location has been reported in the literature. We report a case of lichen sclerosus associated with scleroderma in children, highlighting the importance of dermoscopy in diagnosis. Female patient, 9 years old, white, with asymptomatic hypochromic lesions initially on the hands with subsequent progression to feet liqueb knees, for about 8 months.

Dermatological examination revealed polygonal, pearly papules, with parchment-like escleroatrofivo, which agglomerated on plaques in hands, feet and knees Figure 1. Some of these lesions presented central escleroatrofivo points. On the right wrist and dorsum of the feet there were poorly defined areas of hyperpigmentation and skin atrophy, intermingled with hypochromic lesions described above Figure 2. General physical and laboratory examination showed no alterations.
Dermoscopy of hand, feet and knees lesions showed multiple whitish areas, some surrounded by an erythematous halo, with the presence of whitish amorphous areas and pseudocomedones Figure 3.
On the clinical and dermoscopic findings the diagnosis of extragenital lichen sclerosus associated with localized scleroderma was established. Pearly papules lesions, polygonal, confluent, with parchment-like surface, on the back of the hand. White-pearly papules surrounded by hyperchromic halo, poorly delimited, associated with areas of atrophy, on liqurn back of the foot.
Dermoscopy of the lesions on the back of the hand: Lichen sclerosus LS was first described in the late nineteenth century by Hallopeau. When present in children, the appearance of symptoms occurs between two and five years of age.
Diagnosis is usually clinical and may be supplemented with dermoscopy, with no need for histopathological examination when the lesions are typical. In dermoscopy recent LS lesions are characterized by homogeneous whitish areas with erythematous halo Figure 4with the presence of yellow circles follicular esclerooatrofico – comedo-like openingswhich complies with the histopathologic features of ortohyperkeratosis and follicular plugging.
Dermoscopy showing disease activity: Currently there is still no effective treatment for LS, and the majority of patients are initially treated with potent topic corticosteroids. Alternatives are topic calcineurin inhibitors, topic and systemic retinoid, antimalarial drugs and phototherapy. Dermoscopy is a practical optical tool, easy to handle, which, associated with typical clinical features, can assist in the early diagnosis of LS, with no need for invasive examinations.
