Abstract
Turner syndrome (TS) has been linked to a number of autoimmune conditions, including lichen sclerosus (LS), at an estimated prevalence of 17%. LS is a known precursor to vulvar cancer. We present a case of vulvar cancer in a 44-year-old woman, who had previously complained of pruritus in the area, a known symptom of LS. Histology confirmed a squamous cell carcinoma with underlying LS. Vulvar assessment for the presence of LS should be undertaken regularly as part of the routine assessments proposed for adult TS women. If LS is identified, then the patient should be warned of the increased risk of vulvar cancer progression and should be monitored closely for signs of the condition. LEARNING POINTS: Patients with TS are at increased risk of developing LS.LS is a known precursor to vulvar cancer.TS women with LS may be at risk of developing vulvar cancer and should be offered annual vulvar screening and also be aware of signs and symptoms of early vulvar cancer.
