Living with FLOTCH syndrome

A rare genetic skin condition with white nails and repeated cysts under the skin of the scalp, sometimes with eyelash and nail changes.

Understanding FLOTCH syndrome

FLOTCH syndrome is a rare genetic skin disorder with white nails (leukonychia) and multiple, recurring hair-follicle cysts (pilar cysts).

Some people also have eyelash problems and spoon-shaped nails (koilonychia). Kidney stones have also been reported. It begins in infancy or childhood.

Signs & symptoms

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

  • White nails and nail changes
  • Repeated skin cysts
  • Sparse or abnormal eyelashes
  • Eyelid inflammation (blepharitis)
  • Sensitivity to light (photophobia)
  • Kidney stones

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. Ask which tests can help

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