    Vulvar pruritus in postmenopausal woman


    Correct Answers

    Your most likely diagnosis is: A. Lichen sclerosus

    Your treatment plan is: B. Topical steroids


    Lichen sclerosus is a chronic condition that affects many women. It must be distinguished from other vulvar pruritic conditions such as HSIL of the vulva and vulvar cancer. Lichen sclerosus is mostly a disorder of adult women, but can occasionally be seen in children as well as in men. It is normally found on the genitals and perianal region and often causes itching and soreness. Over time, significant scarring may occur. Typically, there is a wrinkled, cellophane appearance to the skin. As is seen in this patient, purple areas (telangiectasia) may be present.

    An initial biopsy should be considered to confirm the diagnosis of lichen sclerosus and rule out other pruritic causes. Treatment is with potent topical steroid ointment, such as clobetasol 0.05% ointment twice daily for a month, followed by once daily for 2 months, followed by maintenance therapy. Maintenance therapy can consist of a class 1 topical steroid such as clobetasol 0.05% ointment twice weekly to 3 times weekly or a mid-dose steroid such as triamcinolone acetonide ointment 0.1% nightly. Patients should be informed that lichen sclerosus can flare intermittently and they may need to repeat the class 1 steroid intermittently. It is helpful to have a provider do vulva checks every 6 to 12 months. Rarely, lichen sclerosus can be associated with differentiated vaginal intraepithelial neoplasia or cancer. Repeat biopsy is recommended if a suspicious area develops.    

    HSIL of the vulva is most commonly caused by the high-risk types HPV. It can also cause itching. Diagnosis is done with vulvoscopy and directed biopsies. Depending on its location, HSIL is treated in a variety of ways, including laser, topical imiquimod 5%, or excision. 

    SCC may also be associated with high-risk HPV types (previously discussed) or with lichen sclerosus (as  seen in Figure 16) or lichen planus.  Up to 5% of women with lichen sclerosus of the vulva develop invasive SCC.

    Vulvar SCC

    Although vulvar candidiasis can cause vulvar pruritus, that is not the typical appearance. Vulvar candidiasis is often bright red and weepy. Wet mounts and cultures usually reveal pseudo-hyphae. Treatment can be with topical and/or oral fluconazole. Postmenopausal patients with recurrent vulvar candidiasis should be tested for diabetes mellitus.
