Introduction

As pain symptoms from neuroproliferative vestibulodynia (NPV) often arise at initial attempt at tampon insertion or penetrative sex, most vestibulodynia patients present in their 20’s or 30’s. Consequently, individuals who reached this age prior to 2004-when Dr. Bornstein and colleagues delineated the excess mast cell and nerve pathology-had limited opportunity for successful NPV diagnosis and treatment. Menopausal patients often experience vulvar pain with genitourinary syndrome of menopause (GSM) due to the paucity of sex steroid hormonal support of their genital tissues. While symptoms of painful penetration are similar in both of these conditions, NPV is diagnosed when severe allodynia/hyperalgesia is still present with a normal or corrected hormonal milieu. A treatment for NPV is complete vestibulectomy surgery, performed in premenopausal eugonadal patients. However, in hormonally depleted patients with GSM, the vaginal tissue is thinner and less robust making it less optimal for reconstructive surgery.

Objective

To examine the intersection of genitourinary syndrome of menopause and neuroproliferative vestibulodynia symptoms in a subgroup of at-risk patients and to report techniques for optimizing management of this patient population.

Methods

We reviewed charts of two menopausal patients with NPV and report a clinical strategy for successful management.

Results

Two patients, ages 58 and 63 reported histories consistent with NPV during their reproductive years-one with lifelong entrance pain with any insertion and one with pain-free penetration prior to experiencing severe burning upon use of topical miconazole for candidiasis. At presentation, both had entry pain symptoms consistent with GSM and NPV. Since NPV is a diagnosis of exclusion, each was treated for GSM with intravaginal DHEA and vestibular topical compounded testosterone/estradiol cream. After 6 months, vestibular pallor and erythema resolved, however, cotton-tip swab testing scores did not improve. A positive improvement with vestibular anesthesia testing was consistent with NPV. Each underwent a complete vestibulectomy with vaginal advancement flap with successful wound healing and no adverse events despite their age and prior GSM diagnosis. Both patients report “very much better” symptoms on post-op Patient Global Impression of Improvement. Immunohistochemical staining of excised vestibular tissue confirmed a high density of CD117 and PGP9.5 staining consistent with an NPV diagnosis. Each patient has continued their menopause treatments post-op.

Conclusions

We report on two menopausal patients with NPV who had classic symptoms of severe allodynia/hyperalgesia in their reproductive years but who were not managed as NPV patients due to lack of knowledge at that time. Treating the GSM first with hormone replacement may restore health to vaginal tissues, thereby allowing the excised vestibular region to be covered with a vaginal advancement flap. Managing GSM symptoms prior and then undergoing vestibulectomy allowed them to have pain-free penetration.
