Abstract

In order to retrospectively analyse the multi-site involvement pattern of erosive lichen planus patients, we retrospectively reported the clinical and medical data of three patients with erosive lichen planus which involving their vulva, vagina, gingiva, and ear canal. We confirmed the existence of otic lichen planus, and found that it is more common in patients with vulvovaginal-gingival syndrome of erosive lichen planus. Therefore, we propose ‘vulvovaginal-gingival-otic syndrome’ to further describe this rare compound pattern of lichen planus.
