What is the clinical presentation of eczema herpeticum associated with severe eczema?

Eczema herpeticum is a secondary infection caused by the herpes simplex virus in individuals who have atopic dermatitis or severe eczema. The clinical presentation typically includes a rapid progression of the rash, which may become vesicular and can spread quickly over affected areas. This condition is often accompanied by systemic symptoms like fever, malaise, and lymphadenopathy due to the viral infection.

The presence of fever alongside the rapid onset of the rash differentiates eczema herpeticum from other skin manifestations. While localized itchiness and discomfort may occur, the hallmark of this condition is the association with fever and the sudden deterioration of the skin's condition, linking it to the herpetic infection.

Other clinical features might include painful vesicles that can weep or crust over, further emphasizing the infectious nature of the condition in contrast to the original eczema. Recognizing this presentation is crucial for timely management, which may include antiviral medications to control the herpes simplex infection.
