Living with Gastrocutaneous syndrome

A rare skin pigment condition with freckle-like spots and café-au-lait spots, linked to a hiatal hernia and stomach ulcer.

Understanding Gastrocutaneous syndrome

Gastrocutaneous syndrome is a rare condition with darker skin spots along with stomach and eye features.

It features many lentigines (small flat dark spots) and café-au-lait spots (light brown patches), along with hiatal hernia, peptic ulcer, wide-set eyes (hypertelorism), and nearsightedness. GARD says there have been no further descriptions in the medical literature since 1982. It may start in the teen years or adulthood.

Signs & symptoms

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

  • Many small dark spots (lentigines)
  • Light brown patches (café-au-lait spots)
  • Hiatal hernia
  • Stomach or bowel ulcer (peptic ulcer)
  • Nearsightedness (myopia)
  • Wide-set eyes (hypertelorism)

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 digestive system specialists, 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.
