Living with Dyschromatosis universalis hereditaria

A skin condition with scattered dark and light spots all over the body, beginning in infancy or childhood.

Understanding Dyschromatosis universalis hereditaria

Dyschromatosis universalis hereditaria is a skin pigmentation condition with a net-like pattern of dark and light spots all over the body.

People have both darker and lighter flat skin spots (macules) spread across the body. It usually begins in infancy or childhood. Some people also have hearing loss or sun-sensitive skin. Short height has been listed as less common.

Signs & symptoms

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

  • Dark flat skin spots (hyperpigmented macules)
  • Light patches of skin (hypopigmentation)
  • Freckling
  • Café-au-lait spots
  • Hearing loss
  • Sun-sensitive skin

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

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in ABCB6 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
