The prevalence of self-reported medical comorbidities in patients with vulvar lichen sclerosus: A single-center retrospective study.

OBJECTIVE: To compare the demographics and self-reported medical comorbidities of patients with vulvar lichen sclerosus (VLS) with those of women with other vulvar conditions. METHODS: Intake questionnaires for patients presenting to the University of Michigan Center for Vulvar Diseases between 1996 and 2019 were entered into a de-identified database (n = 1983). Responses to questions about thyroid disease, urinary symptoms and signs, gastrointestinal conditions, and pain conditions were collected. RESULTS: A total of 1983 women, including 865 patients with VLS and 1118 patients without VLS were enrolled. Pearson's χ2 analysis showed that age, hypertension, anorectal fissures, peptic ulcer disease/gastroesophageal reflux disease, urinary incontinence, fibromyalgia, thyroid disease, kidney problems, liver problems, and cancer were significantly associated with VLS when compared between the VLS and non-VLS groups (P < 0.01). However, multiple regression analysis demonstrated that only age, thyroid disease, and anorectal fissures were strongly associated with VLS (P < 0.01). CONCLUSION: Increasing age, thyroid disease, and anorectal fissures were significantly associated with VLS. The association between anorectal fissures and VLS likely represents a sequela of the disease rather than a true comorbidity.
