Living with Liver mesenchymal hamartoma

A tumor-like growth with many cysts in the liver that forms before birth and often shows up as a swollen belly.

Understanding Liver mesenchymal hamartoma

Liver mesenchymal hamartoma is a multicystic, tumor-like growth that arises from the liver during fetal development.

It usually appears as a mass in the belly with swelling or bloating (abdominal distention). GARD says the outlook is usually good after the mass is removed (resection).

Signs & symptoms

GARD doesn't list a separate symptom list. Its summary describes these signs:

  • Mass in the belly
  • Swollen belly (abdominal distention)

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 cancer specialists and digestive system specialists.

  3. Ask which tests can help

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