Living with Acroerythrokeratoderma

A condition, also called mal de Meleda, in which the skin of the palms and soles becomes thick, hard, and callused.

Understanding Acroerythrokeratoderma

Acroerythrokeratoderma, also called mal de Meleda, is a rare skin disorder that begins in early infancy.

The skin of the palms and soles becomes thick, hard, and callused, and the thickening can spread to the back of the hands and feet, wrists, and ankles. Rough pads can form on the joints. Some people have repeated fungal infections that cause a strong odor. Other features include short fingers and toes, nail changes, red skin around the mouth, and heavy sweating. GARD lists onset as infant and child.

Signs & symptoms

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

  • Thick, hard skin on palms and soles
  • Redness of the skin
  • Excessive sweating
  • Rough pads on joints
  • Joints that cannot straighten
  • Fungal infections in thickened 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 SLURP1 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.
