Living with Melkersson-Rosenthal syndrome

A rare syndrome with repeated facial nerve weakness, swelling of the face and lips, and a grooved tongue.

Understanding Melkersson-Rosenthal syndrome

Melkersson-Rosenthal syndrome (MRS) is a rare, inherited condition that affects the nervous system and skin.

It has three main features: repeated weakness of the facial nerve, swelling episodes in the face and lips, and deep grooves in the tongue. Most people have only one or two of these. It is more common in females. It can be linked with Crohn's disease or sarcoidosis in some cases. It can start in childhood.

Signs & symptoms

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

  • Facial weakness (facial palsy)
  • Swelling of the face and lips
  • Grooved tongue (furrowed tongue)
  • Swelling around the eyes
  • Inflamed lips (cheilitis)
  • Enlarged tongue (macroglossia)

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 and skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
