Is the 2003 ISSVD terminology and classification of vulvodynia up-to-date? A neurobiological perspective

This paper aims to determine if the 2003 International Society for the Study of Vulvovaginal Disease (ISSVD) terminology and classification of vulval pain is up-to-date, according to a current and widely accepted neurobiological pain classification, which divides pain into nociceptive, inflammatory and pathological pain with the latter subdivided into neuropathic and dysfunctional pain. Nociceptive pain is protective, adaptive, high-threshold pain provoked by noxious stimuli. Inflammatory pain is protective, adaptive, low-threshold pain associated with peripheral tissue damage and inflammation. Pathological pain is non-protective, maladaptive, low-threshold pain caused by structural damage to the nervous system (neuropathic pain) or by its abnormal function (dysfunctional pain). The 2003 ISSVD vulval pain classification should be revised in terms of current neurobiological pain information. Inflammatory vulval pain occurs as a result of specific infectious, inflammatory and neoplastic disorders. Neuropathic vulval pain arises following a specific neurological disorder, responsible for structural damage to the nervous system. Vulvodynia is dysfunctional vulval pain, caused by abnormal function of the nervous system itself.
