Topical imiquimod adverse event: Beyond the local skin reaction—A case report

Abstract

Imiquimod is a well-known topical treatment for its efficacy against various skin conditions. While generally well-tolerated, adverse reactions like local skin irritation are common. However, severe systemic effects such as Stevens–Johnson syndrome (SJS) are rare, but possible. We present the case of an 82-year-old male who developed SJS following topical Imiquimod therapy for basal cell carcinoma. Despite minimal systemic absorption, serious reactions can occur, warranting caution. Prompt recognition and discontinuation of treatment are crucial for managing such rare but severe adverse events. This case underscores the importance of informed consent and vigilant monitoring for adverse reactions associated with Imiquimod therapy.
