Eczema herpeticum is a condition that occurs when an eczema skin rash becomes infected with the herpes simplex virus. Most often people with this virus only get cold sores on the lips and mouth area. However if that person also has a skin condition such as eczema, sores can appear anywhere on the body. Eczema herpeticum symptoms are usually severe and can include a high fever and small blisters that can sometimes be filled with a liquid pus.

Dyshidrotic eczema (also known as dyshidrosis or pompholyx) is identified by blisters which mainly show up on the feet and hands of the sufferers. These blisters are thick and can cause severe pain and itching. Although the condition is not contagious the discomfort and appearance of the eczema symptoms can cause great physical and emotional distress.
