Living with Littoral cell angioma

A very rare tumor of the spleen's blood vessels that is usually non-cancerous and often causes no symptoms.

Understanding Littoral cell angioma

Littoral cell angioma of the spleen is a very rare vascular tumor of the spleen.

Most reported cases have been non-cancerous (benign), and many cause no symptoms. It is often found by chance during an exam or tests done for other reasons. It affects men and women equally and mostly occurs in middle-aged adults and occasionally in children. It is hard to diagnose by imaging, so diagnosis is usually confirmed by biopsy.

Signs & symptoms

Many people have no symptoms. When symptoms occur, GARD says they may include:

  • Belly pain
  • Enlarged spleen (splenomegaly)
  • Anemia (low red blood cells)
  • Low platelet count (thrombocytopenia)

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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