Resolution of vulvitis circumscripta plasmacellularis with topical imiquimod: two case reports.

Vulvitis circumscripta plasmacellularis (VCP) is a rare but well-described entity. It is notorious for its recalcitrant nature to various modalities of treatment. Intralesional interferon-alpha showed some promise, with complete resolution, but is coupled with the side-effect of myelosuppression. Topical imiquimod is a novel immune response modifier with the ability to induce the production of interferon-alpha. In this paper, we report two cases of VCP whose lesions were resistant to antibiotics, topical and oral corticosteroids, but resolved after a treatment trial with imiquimod.
