Eruptive epidermoid cysts are a rare adverse event of imiquimod treatment for basal cell carcinoma. Up to date, 8 cases have been described in the literature. We present the case of a 75-year-old Caucasian woman with recurrent basal cell carcinoma on the nose. After multiple excisions and treatment with vismodegib, imiquimod 5% cream was administered 5 times per week over 6 weeks. Two months after the end of treatment, the patient presented with eruptive epidermoid cysts.
