Lichen sclerosus (LS) et atrophicus is a disease of unknown etiology, although hereditary, endocrine, and autoimmune factors are known to be involved. While the anal and genital regions are predominantly affected, only 2.5% of patients present with extragenital lesions, particularly of the trunk, neck, and upper limbs. The possible relationship between lichen sclerosus et atrophicus and both lichen planus (LP) and localized scleroderma (morphea) has not been clearly established, although in a number of cases, several of these conditions have been found simultaneously. We report the case of a 31-year-old woman with LS lesions affecting the neck, upper back, wrist and dorsum of the feet. The unusual character of this presentation is pointed out, along with its clinical similarity to LP.

    ABSTRACT: Background  Little is currently known about the dermoscopic patterns of genital and extragenital lichen sclerosus (LS). In order to evaluate and compare the dermoscopic and histopathologic patterns of genital and extragenital lichen sclerosus, a retrospective analysis of clinical, dermoscopic and histopathologic features of genital and extragenital LS, collected between March 2010 and December 2011 at four dermatology clinics in Greece, Italy, Serbia and Uruguay was performed. Observations  A total of 29 lesions from 14 (mean age 62.8 years) and 12 (mean age 53.5 years) patients with genital and extragenital LS, respectively were analyzed. Mean duration of disease was 3.5 years for genital and 1.8 years for extragenital LS. White-yellowish structureless areas were seen in all cases of genital and extragenital LS; however linear vessels occurred at higher frequency in genital than in extragenital lesions (85.7% vs. 33.3%, respectively). Extragenital LS revealed two different time-related patterns: keratotic plugs were more prevalent in lesions with short duration (<2 years), whereas longer persisting lesions appeared atrophic and revealed fine chrysalis structures. Conclusions  Our morphologic study provides novel insights into the morphologic diversity of LS at different body sites and different stages of progression.

    ABSTRACT: Lichen sclerosus et atrophicus (LSA) also known as Csillag's disease, characterized by small, porcelain white, sclerotic areas occur at any site on the skin including mucosa. There is strong association of autoimmune disorders with LSA. Lichen planus (LP) is an inflammatory, papulosquamous disorder characterized by erythematous to violaceous, flat topped, polygonal, pruritic papules distributed mainly on flexural aspects like wrist, around ankles, lumbar region, trunk and neck and also involves mucous membranes, hair, and nail. LP and LSA share similar clinical and pathological features. There have been a few reported cases in the literature of the coexistence of LP and LSA. We reported a case of 39-years-old female having LSA with cutaneous distribution and morphologically simulating LP.
