What is the medical term for lesion associated with chickenpox?

The medical term for a lesion associated with chickenpox is known as a varicella vesicle. Chickenpox, also medically referred to as varicella, is caused by the varicella-zoster virus (VZV). It is a highly contagious disease characterized by an itchy rash of small, fluid-filled blisters, known as varicella vesicles, that appear on the skin. The rash usually starts on the chest, back, and face, then spreads to the rest of the body. The blisters eventually crust over and heal within a few weeks, leaving behind temporary scars.
