Vulvovaginal-gingival lichen planus: Association with lichen planopilaris and stratified epithelium-specific antinuclear antibodies

Abstract

Vulvovaginal-gingival lichen planus (VVG-LP) consists of a triad of symptoms: vulval, vaginal and gingival lichen planus lesions. The aim of this study was to analyse the prevalence of lesions in various anatomical locations in patients with VVG-LP. The study included 126 consecutive patients with lichen planus. Sixteen (12.7%) patients fulfilled the criteria of VVG-LP. In 12/16 (75%) patients with VVG-LP scalp lesions were also observed. Stratified epithelium-specific antinuclear antibodies (SES-ANA) and anti-ΔNp.3α antibodies were detected in 10/16 (75%) patients with VVG-LP and in 15/110 (13.6%) patients with other forms of lichen planus (p < 0.05). In conclusion, VVG-LP is frequently associated with lichen planopilaris. The new entity may be termed “vulvovaginal-gingival-pilar lichen planus” and our study indicates that SES-ANA is a marker of this type of lichen planus with extensive, severe and refractory- to-therapy involvement of the mucous membranes, skin and scalp.
