Frequency of Genital Involvement in Women with Oral Lichen Planus in Southern Iran

الملخص EN

Background.

Lichen Planus is a chronic mucocutaneous disease of immunological basis and unknown etiology.

women with oral lichen planus may have concomitant manifestations in vulvovaginal areas.

Objective.

To determine the frequency and risk factors of genital involvement in a group of Iranian women affected by oral lichen planus.

Methods.

Thirty-six women with clinical and histopathological diagnosis of oral lichen planus were evaluated for demographic, historical, and clinical parameters of the oral disease.

All the patients were referred for careful vulvovaginal examination, as well as histopathological assessment upon clinical indication.

Results.

Nineteen patients complained from genital symptoms but the number of women with the final diagnosis of genital lichen planus (n=2) was too small to show any correlation with the parameters evaluated.

Conclusion.

In spite of low genital involvement possibly due to inadequate patient population, lack of follow-up visits, and contribution of genetic or ethnic factors, for conservative patient care, women with the oral lichen planus in particular those having some relevant genital symptoms, should preferably be referred for careful vulvovaginal examination.

Multicenter cohort studies on women of different geographical regions or ethnicities who have genital lichen planus alone or in combination with other common sites are encouraged.
