Successful treatment of three cases of primary extramammary Paget's disease of the vulva with Imiquimod--proposal of a therapeutic schedule.

ABSTRACT

BACKGROUND/AIM: Extramammary Paget's disease (EMPD) is an intraepidermal adenocarcinoma of apocrine gland-bearing skin. Although surgery remains the mainstay of treatment, loss of tissue function and high recurrence rates have been reported. Recently, topical Imiquimod has been shown as a safe and effective treatment option for extramammary Paget's disease. METHODS: Three patients diagnosed of EMPD of the vulva were treated with a daily application of 5% Imiquimod cream for three weeks, followed by an every other day application for an additional three weeks. RESULTS: Complete clinical and histological remission of the disease was achieved in the three patients. Mild irritation and tenderness were observed as the only side effects. CONCLUSION: Based on our results, we consider that Imiquimod cream is a safe and effective therapeutic option for the treatment of vulvar EMPD. These promising results warrant further studies to determine the real efficacy and safety of Imiquimod 5% cream for the treatment of this uncommon disease.
