Living with SAPHO syndrome

An inflammatory condition combining joint, skin, and bone problems such as acne, pus-filled blisters, and bone overgrowth.

Understanding SAPHO syndrome

SAPHO syndrome is a condition with any mix of joint inflammation, acne, pus-filled blisters, bone overgrowth, and bone inflammation.

The name stands for synovitis, acne, pustulosis (often on the palms and soles), hyperostosis, and osteitis. People may have any combination of these. It can occur at a variety of ages.

Signs & symptoms

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

  • Joint pain and arthritis
  • Acne
  • Pus-filled blisters on palms and soles
  • Bone pain
  • Bone overgrowth (hyperostosis)
  • Chest pain

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