My daughter has had eczema for 3 years. She recently developed a new rash, which our doctor said was molluscum. What is this?

Molluscum, also called molluscum contagiosum, is a type of tiny
wart in the skin that looks rather like small, translucent blisters.
These are caused by an infection with a poxvirus. Some people
refer to them as water warts, although they are in fact solid. They
are dome shaped and often have a small depression or punctum
on the top. Molluscum is common in children and young adults,
and is more frequently seen in patients with eczema, perhaps
because the process of scratching causes the virus to spread. As
with warts, the blisters eventually clear on their own, which is just
as well because treatment can be painful – for example, using liquid
nitrogen spray to freeze them off. They are not serious and can be
safely left alone.
