Definition

Noun: 1. A chronic inflammatory collagen disease affecting connective tissue (skin or joints): "LE" is a medical abbreviation, most commonly for Lupus Erythematosus. It refers to a group of autoimmune diseases where the body's immune system attacks its own healthy tissues, particularly affecting connective tissues in the skin, joints, and often internal organs.

Usage Notes

• "LE" is primarily used in formal medical contexts, such as in clinical notes, diagnoses, and scientific literature.
• It is an abbreviation and is typically written in uppercase letters (LE).
• In spoken language, the full term "Lupus Erythematosus" is more common than saying the letters "L-E."

Examples

• Noun:
  • The patient's skin biopsy was consistent with LE. (The patient's skin biopsy showed signs of Lupus Erythematosus.)
  • Systemic LE (SLE) can affect multiple organ systems. (Systemic Lupus Erythematosus can impact many of the body's organs.)
  • Discoid LE primarily causes skin lesions. (Discoid Lupus Erythematosus mainly results in skin sores.)

Advanced Usage

• "LE cell": A type of white blood cell (neutrophil) that has engulfed the nucleus of another cell, which is a characteristic laboratory finding historically associated with Lupus Erythematosus.
  • The presence of LE cells in the blood test supported the diagnosis.

• DLE: Abbreviation for Discoid Lupus Erythematosus, a form primarily affecting the skin.
