Ingenol mebutate (IM) is approved for the treatment of actinic keratosis and induces cell death in precancerous lesions. The efficacy of IM in the treatment of genital warts was investigated in a therapy-refractory patient. The 74-year-old male was treated with IM gel for three consecutive days. Treatment course and efficacy were evaluated by clinical inspection and non-invasive diagnostics namely optical coherence tomography (OCT) and reflectance confocal microscopy (RCM). Within 24 to 48 hours IM induced a strong local inflammatory reaction. One week later a complete response was observed. OCT and RCM showed a strong reaction after treatment with erosions, swelling of cells, and a subepidermal dark band in representative lesions. IM has the advantage of a short treatment period in contrast to other topical treatments and shows a promising clinical outcome. Larger studies are needed to validate the data.
