Nonsyndromic multiple basal cell carcinomas successfully treated with imiquimod 5% cream.

This report describes the case of a 60-year-old man with nonsyndromic multiple basal cell carcinomas that responded to imiquimod 5% cream. The patient had no additional anomalies suggesting any syndromes associated with multiple basal cell carcinomas. By applying the agent 5 times a week for 20 weeks, we obtained good clinical results, and we confirmed the improvement with histopathologic examination.
