Final answer:
A viral skin lesion that can recur after removal is a herpes simplex virus infection. The virus remains dormant in nervous tissue and can reactivate, causing skin lesions such as cold sores or genital herpes outbreaks. The immune response resolves the lesions, but the viruses remain in the body.
Step-by-step explanation:
A viral skin lesion that can recur after removal is a herpes simplex virus infection. The virus can remain dormant in nervous tissue for months or even years, and under certain conditions, it can reactivate and cause skin lesions. This can happen with cold sores on the lips or genital herpes outbreaks. The immune response destroys the viruses in the skin, resolving the lesions in a few days or weeks. However, the viruses remain in the nervous tissue for life, leading to intermittent appearances of the outbreaks.
