Cantharidin application is the treatment of choice for extensive Molluscum Contagiosum.
Molluscum Contagiosum is caused by a viral infection of the skin. The condition is limited to the skin and does not spread through the blood, but from direct contact with an infected area.
It is a very common condition that can affect both adults and children. Children with eczema is especially susceptible to infection. The eczematous areas itself are often involved.
Molluscum Contagiosum always clears up by itself eventually, but can be distressing and unsightly while it is still present. Most people therefore prefer to treat it anyway.
It is very important to choose a treatment option with no significant risk of scarring. Liquid nitrogen therapy (freezing) and surgical removal (curetting) both have a risk of leaving a scar. Aldara treatment takes weeks to months to complete and is not always successful.
Cantharidin application for Molluscum is painless to apply and heals without scarring. The reason that it heals without scarring is because Cantharidin does not affect the dermis, only the epidermis.
After application a small blister will form within 24-48 hours. This blister lifts the Molluscum off the underlying dermis. A small scab will then form and the healing process is normally complete in 7-10 days.
The procedure for treating warts with Cantharidin is similar, except that certain warts should be shaved or pared down before application of Cantharidin.
