Abstract
Oral lichen planus (OLP), a mucocutaneous chronic inflammatory disease, is conventionally managed using topical corticosteroid therapy. Given the fact that OLP is strongly linked to angiogenesis, anti-angiogenic drugs, such as bevacizumab, might be introduced as an alternative treatment for contraindicated, non-responsive patients. The aim of the present study was to report the short-term effectiveness and safety of intralesional bevacizumab injection in the management of atrophic/erosive OLP. A case series study was conducted in patients with atrophic/erosive OLP in the buccal mucosa, assigned to receive either 2.5 mg of bevacizumab, by intralesional injection (n = 20, test), or topical 0.1% triamcinolone acetonide ointment (n = 20, control). The size, score, and pain intensity of the lesions were assessed pre- and post-treatment. Tissue biopsies were collected for histopathologic, immunohistochemical, and ultrastructural examination. After 1 wk, the test group had significant reductions both in lesion seize and in pain scores compared with controls. A marked decrease in vascular endothelial growth factor (VEGF) and interleukin-8 immunoexpression was noted in tissue biopsies from bevacizumab-treated lesions compared with control lesions. Furthermore, ultrastructural examination of OLP tissue specimens revealed significant healing signs associated with bevacizumab treatment. Short-term data suggest that intralesional bevacizumab injection effectively and safely achieved resolution of atrophic/erosive OLP lesions without disease exacerbations during a 3-month follow-up period.
