Living with Hereditary hypotrichosis with recurrent skin vesicles

A very rare inherited condition with thin or missing hair and small fluid-filled blisters that burst.

Understanding Hereditary hypotrichosis with recurrent skin vesicles

Hereditary hypotrichosis with recurrent skin vesicles is a very rare inherited hair loss condition with recurring small blisters.

Hair is sparse, fragile, or absent on the scalp, eyebrows, eyelashes, underarms, and body. Fluid-filled blisters (vesicles) form on the scalp and other areas and regularly burst, releasing watery fluid. GARD says it was described in one family. It starts in the newborn period or infancy.

Signs & symptoms

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

  • Sparse hair on the scalp
  • Sparse eyebrows and eyelashes
  • Little body or underarm hair
  • Small blisters that burst
  • Rough, bumpy skin around hair follicles
  • Sore corners of the mouth

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 DSC3 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
