Options for field treatment include topical chemotherapy with 5-FU or photodynamic therapy. Imiquimod has limited utility in diffuse disease because adverse effects increase when this agent is applied to large surface areas. If 5-FU therapy is planned, remove any hyperkeratotic lesions with a curette just before beginning therapy, to enhance penetration of the medication to the basal layer.
