Definition

1. Noun:
   • A medical condition: Eczema herpeticum is a severe and potentially serious skin infection. It occurs when the herpes simplex virus (HSV) infects skin that is already affected by eczema or other inflammatory skin conditions. The condition is characterized by a feverish state and the widespread eruption of numerous small, fluid-filled blisters (vesicles). It is most commonly observed in children, particularly those with atopic dermatitis.

Usage Examples

• Noun:
  • The pediatrician diagnosed the child's sudden, painful rash as eczema herpeticum.
  • Eczema herpeticum requires prompt medical attention to prevent complications.
  • A high fever accompanied the vesicular eruption, which is typical of eczema herpeticum.

Advanced Usage

• Clinical Context: The term is used almost exclusively in medical and dermatological contexts to describe this specific viral complication of pre-existing eczema.
  • The differential diagnosis included impetigo and eczema herpeticum.

Variants and Related Words
