Superficial Basal Cell Carcinoma of the Face Successfully Treated with Ingenol Mebutate 0.05% Gel: Case Report and a Review of the Literature

A 64 year-old Caucasian male patient with a long history of ultraviolet light exposure and multiple actinic keratoses presented with a large, erythematous, and scaly plaque on his forehead. Biopsies revealed superficial basal cell carcinoma (sBCC). Because the patient wanted the shortest possible topical regimen, his sBCC was treated with two overnight ingenol mebutate (IM) 0.05% gel applications. He tolerated the local skin reaction (LSR) well, and at approximately six weeks post-treatment, biopsies showed no evidence of sBCC. The patient was happy with the cosmetic outcome and has remained free of clinical recurrence for 18 months. Although IM gel is only FDA approved for the treatment of actinic keratosis, it has also been used off-label to treat other epithelial lesions, including basal cell carcinoma (BCC), anogenital warts, and Bowen’s disease. One clinical trial, multiple case series and case reports, and now this report, have demonstrated IM’s utility in treating BCC. IM treatment is therefore a promising alternative to surgery for select BCC, with major advantages, including a short treatment duration and generally favorable cosmetic outcome.
