Superficial basal cell carcinoma treated with imiquimod 5% topical cream for a 4-week period: a case series.

Basal cell carcinoma (BCC) is a malignant cutaneous neoplasm with a tendency to spread locally and with several clinical and histological subsets. We studied 82 patients with a clinical diagnosis of superficial BCC on different anatomical locations, to whom imiquimod 5% cream was administered on a low-frequency regime (three times a week for 4 weeks), and who were followed up 2 years after completion of treatment. Clinical clearance rate at 1 and 2 years were 89% and 85%, respectively. We conclude that imiquimod seems to be an appropriate therapeutic alternative for the treatment of superficial BCC in patients with associated comorbidities.
