Topical Imiquimod and Subsequent Erythema Multiforme
J Osteopath Med; 120(1): 45-48
Topical imiquimod is commonly used in the nonsurgical management of actinic keratosis and superficial basal cell carcinoma. Although adverse effects have been limited primarily to local irritation, another rare adverse reaction is erythema multiforme. We present a case of erythema multiforme involving the oral mucosa, trunk, and extremities that followed broad application of topical imiquimod for the management of suspected superficial basal cell skin cancers and actinic keratosis. The patient had used imiquimod previously without complication. Cessation of use and systemic corticosteroids resulted in prompt clearance.
