Verruca vulgaris is an infection of human papilloma virus and minute wound of the skin is the penetrating route of the virus. It is common in the areas of the hands and feet and once infected, the lesion becomes a warty bump. Molluscum contagiosum, on the other hand, is caused by a poxvirus, the molluscum contagiosum virus, and it frequently looks as if there is water inside the bump. Molluscum contagiosum usually disappear on its own within a few months to a few years, but it may also spread to other body areas and to others. It can also trigger eczematous changes.

The management of verruca vulgaris includes cryotherapy with liquid nitrogen,  oral Chinese medicine called Yokuininto (adlay extract), and topical speel plaster (salycylic acid patch).  Molluscum contageosum may be taken at the initial visit if the number is low, but the use of Penles tape (Lidocaine patch) is suggested to mitigate the pain in the procedure. For those children who are reluctant to cooperate in the mechanical removal, there is another way of removal.
