Superficial basal cell carcinoma on face treated with 5% imiquimod cream

Imiquimod, an immune response modifier, is known to possess both anti-viral and anti-tumor effect. We report our experience of treating a large superficial spreading basal cell carcinoma with 5% imiquimod cream. A 65-year-old male had an asymptomatic, hyperpigmented, slowly progressive, indurated, 3 x 4 cm plaque on the left cheek for two months. Biopsy from the lesion showed features of basal cell carcinoma. The patient was treated with imiquimod 5% cream, topically three times a week for six months with complete resolution of the lesion and without any side-effects. There was no clinical or histological recurrence after three months of stopping the treatment.
