Living with Acrokerato-elastoidosis

A rare skin condition with small, yellowish, thickened bumps on the palms of the hands and soles of the feet.

Understanding Acrokerato-elastoidosis

Acrokerato-elastoidosis is a rare skin condition with small thickened bumps on the palms and soles.

The bumps are small, round to oval, and yellowish. They are most often on the palms and soles, and in severe cases can spread to the backs of the hands and feet. It can occur on its own or run in families. GARD lists onset as teenager and adult.

Signs & symptoms

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

  • Yellowish thickened bumps (papules)
  • Thickened skin on palms and soles
  • Thick upper layer of skin
  • Fragmented elastic fibers in the skin
  • Hard, thick skin patches

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 CCDC91 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Foundation for Ichthyosis and Related Skin Types may keep lists of experts for this condition.
