Aluminum-based salts: an unorthodox but simple way to treat molluscum contagiosum and cutaneous warts.

Molluscum contagiosum and human papillomavirus (HPV) are very common cutaneous infections with worldwide distribution, yet treatment options remain limited. Traditional therapies are invasive and have a high rate of recurrence, and newer topical agents available are costly. Here I discuss evidence supporting the hypothesis that the aluminum-based salts, utilized in the antiperspirant industry since the early 1900s, could have a therapeutic effect on skin lesions due to molluscum contagiosum, HPV and possibly other viruses. Clinical trials in this area are needed.
