Living with Erythema elevatum diutinum

A skin condition with red, purple, brown, or yellow bumps caused by inflammation of small blood vessels.

Understanding Erythema elevatum diutinum

Erythema elevatum diutinum (EED) is a skin disorder linked to inflammation of small blood vessels (vasculitis).

People get red, purple, brown, or yellow bumps of different sizes on or just under the skin. They are mainly on the elbows, knees, ankles, hands, and fingers. Some people also have joint pain but few other symptoms. It can occur at any time in life. Diagnosis is by symptoms and a skin biopsy.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Red, purple, brown, or yellow skin bumps
  • Skin rash
  • Joint pain
  • Blisters on the skin
  • Inflamed small blood vessels in the skin

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
