2015 Consensus Terminology and Classification of Persistent Vulvar Pain and Vulvodynia
A. Vulvar pain caused by a specific disorder*• Infectious (eg, recurrent candidiasis, herpes)• Inflammatory (eg, lichen sclerosus, lichen planus, immunobullous disorders)• Neoplastic (eg, Paget disease, squamous cell carcinoma)• Neurologic (eg, postherpetic neuralgia, nerve compression or injury, neuroma)• Trauma (eg, female genital cutting, obstetric)• Iatrogenic (eg, postoperative, chemotherapy, radiation)• Hormonal deficiencies (eg, genitourinary syndrome of menopause [vulvovaginal atrophy], lactational amenorrhea)B. Vulvodynia—Vulvar pain of at least 3 months’ duration, without clear identifiable cause, which may havepotential associated factors
The following are the descriptors:• Localized (eg, vestibulodynia, clitorodynia) or Generalized or Mixed (Localized and Generalized)• Provoked (eg, insertional, contact) or Spontaneous or Mixed (Provoked and Spontaneous)• Onset (primary or secondary)• Temporal pattern (intermittent, persistent, constant, immediate, delayed)

Familiality Analysis of Provoked Vestibulodynia Treated by Vestibulectomy Supports Genetic
Predisposition
• 183 potential vestibulectomy probands were identified using CPT codes
• Relative risk of vestibulectomy was elevated in first-degree (20 [6.6-47], P < .00001), second-degree (4.5 [0.5-16], P = .07), and third-degree female relatives (3.4 [1.2-8.8], P = .03)
• Suggests that vestibulodynia treated by vestibulectomy has a genetic predisposition

Conclusion
• Increased expression of ERα in the vulvar vestibular
mucosa in patients with provoked vestibulodynia in the
absence of an altered epithelial morphology
For women aged <50 years of age, OC use did not increase the risk of subsequent vulvodynia.

Mast Cells
• Bornstein et al. (2004) found significant increase in inflammatory infiltrate, number of mast cells and degranulated mast cells in vestibulitis patients (N=40) compared to normal controls (N=7, ages 18-48)
• Regauer et al. (2015) evaluated 35 patients with vulvodynia
-Median age was 24 years (ranged from 18 to 70 years).
-Control tissues obtained from autopsies (? number)
-Only 20/35 vulvodynia specimens showed a T-lymphocyte dominant inflammatory infiltrate on HE-stained sections, but all showed mast cells. 4/35 biopsies showed <10 mast cells/mm2, 15/35 specimens 40–60 mast cells/mm2 and 16/35 specimens >60 mast cells/mm2 (average 80/mm2). Control tissue contained typically <10 mast cells.

Heightened Pelvic Floor Muscle Tone and Altered Contractility in Women With Provoked Vestibulodynia
Evaluated the passive component of the PFM tone in women with PVD
Findings show that women with PVD sustaining quiescent muscle activity during stretching still presented greater passive forces, stiffness, and hysteresis than asymptomatic controls
Women with PVD showed muscle over-activation as well as persistent alterations in muscle viscoelastic properties

Vulvodyniaand the Brain
• On MRI, 24 vestibulodynia patients displayed greater levels of activation during thumb stimulation within the insula, dorsal mid-cingulate, posterior cingulate and thalamus compared to controls (P<0.005 corrected)
• The augmented brain activation in VVD patients in response to a stimulus remote from the vulva suggests central neural pathology in this disorder
