Successful Treatment of Relapsing Bowen's Disease with Ingenol Mebutate: The Use of Dermoscopy to Monitor the Therapeutic Response

摘要

Ingenol mebutate (IM) has recently been approved for the topical treatment of actinic keratoses. It appears to have a dual mechanism of action: rapid necrosis after gel application and a subsequent immune-mediated response, which targets any residual dysplastic epidermal cells. We report the successful treatment of a woman, who had been relapsing into Bowen's disease (BD) on her right forefinger for 8 years. During her clinical history, she had received an allogeneic, HLA-identical stem cell transplant for myeloproliferative syndrome with a JAK2V617F mutation and lobectomy of the pulmonary right lower lobe for adenocarcinoma. We used dermoscopy to monitor the therapeutic response of BD. We discuss IM gel as a possible therapeutic option for BD. (C) 2016 S. Karger AG, Basel
