| Abstract: | Vulvar lichen sclerosus (VLS) is an uncommon, chronic inflammatory skin disease lacking clinical data of large sample size in China. This study was intended to provide missing data on this condition through investigating the clinical characteristics of Chinese VLS patients. The medical records of 129 VLS patients from our vulvar outpatient clinic were analyzed with SPSS version 18.0 software. The age of onset followed a normal distribution, with the peak at 25–30 years. Of all cases, the incidence rate during the postmenopausal period was 14.0% with an average duration of 9.22 years. The most frequently involved site was the bilateral labia minora (71.3%). Itching was the principal symptom (94.6%); meanwhile, patients with severe itching more commonly experienced longer duration, flaring at night, hyperkeratotic lesions or rashes on the posterior commissure than those with mild to moderate itching (P < 0.05). Furthermore, 60% of the enrolled patients suffered from sexual dysfunction. The major sign was pallor (92.2%), followed by hyperkeratosis (55.0%) and atrophy (40.3%). The patients with atrophy had a significantly longer duration of the disease, and the older patients presented more frequently with edema in the area of lesions (both P < 0.05). Of our patients, 9.3% suffered concomitantly from autoimmune diseases, mostly thyroid with one case being complicated by vulvar squamous cell carcinoma (SCC). In our study, the severity of pruritus was partly related to clinical manifestations. Moreover, Chinese patients could have developed VLS mostly in the reproductive period, with less complications of autoimmune diseases or SCC. |
