Living with Papillon-Lefèvre syndrome

A rare inherited condition with thick skin on the palms and soles and severe gum disease starting early in life.

Understanding Papillon-Lefèvre syndrome

Papillon-Lefèvre syndrome (PLS) is a rare condition that combines thick skin on the palms and soles with early-onset gum disease.

It is a type of ectodermal dysplasia, which affects skin, teeth, and nails. Severe gum disease (periodontitis) starts early and can lead to early loss of baby teeth. Recurrent skin infections have also been reported. Signs appear from birth through childhood.

Signs & symptoms

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

  • Thick skin on palms and soles
  • Severe gum disease (periodontitis)
  • Early loss of baby teeth
  • Recurring skin infections and abscesses
  • Poorly formed nails
  • Frequent respiratory infections

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 allergy and immune system specialists, genetic specialists, gum, teeth and mouth specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in CTSC 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

    National Foundation for Ectodermal Dysplasias and Immune Deficiency Foundation may keep lists of experts for this condition.
