About Pediatric Thrombocytosis

Pediatric thrombocytosis is a blood disorder marked by too many platelets circulating in the bloodstream. Platelets are formed in the bone marrow (the red spongy material in the bones) along with red blood cells (which carry oxygen) and white blood cells (that fight infection). Platelets are responsible for clotting (or “plugging”) blood when there’s injury to the blood vessel. When platelets are high, abnormal bleeding can result.

The renowned care teams and researchers at Nemours Center for Cancer and Blood Disorders work together with other top specialists to care for children with thrombocytosis, from the mild to the most severe cases.


Types of Pediatric Thrombocytosis We Treat

Pediatric thrombocytosis is classified as “primary” or “secondary”:
  • Primary thrombocytosis (also called “essential thrombocythemia”) in children is very rare and is caused by an abnormality in the bone marrow.
  • Secondary pediatric thrombocytosis is more common, and is often referred to as “reactive” because it’s due to an underlying medical condition such as anemia (iron deficiency), cancer, infections or surgery.

Diagnosing Thrombocytosis in Children

Signs & Symptoms of Thrombocytosis

Symptoms of primary thrombocytosis in children vary widely depending on the disorder, but can include:

  • dizziness
  • weakness
  • headache
  • prolonged bleeding
  • bloody stools
  • tingling/redness in the hands and feet
  • enlarged liver and/or spleen
  • easy bruising

Sometimes, however, there are no symptoms at all.


Testing & Evaluations

If your child possibly has thrombocytosis — whether it’s primary thrombocytosis (essential thrombocythemia) or secondary thrombocytosis — Nemours’ experienced cancer and blood disorder care team works together to quickly and appropriately diagnose what’s causing disease through a variety of tests and procedures, including:

  • thorough physical examination and medical history
  • blood tests
  • bone marrow aspiration and biopsy

Treating & Caring for Children With Thrombocytosis

Your Child's Comprehensive Thrombocytosis Care Team

If we discover thrombocytosis, our multidisciplinary (collaborative) team plans the most effective treatment personalized to your child’s needs and related health conditions. 

In addition to an experienced, compassionate nurse coordinator (who provides your child and family support, education and care coordination), Nemours’ pediatric cancer and blood disorder teams include: 

  • hematologists (blood disorder specialists)
  • oncologists (cancer doctors)
  • cardiologists (heart specialists) 
  • pathologists (diagnose diseases by examining body tissues, fluids and organs)
  • geneticists (perform genetic counseling and testing)
  • interventional radiologists (perform image-guided minimally-invasive procedures)
  • behavioral health specialists (psychologists and psychiatrists)
  • registered dietitians (nutrition specialists)
  • hematology nurses (registered nurses specializing in blood disorders in children)  

Your care team is here to provide your family with ongoing support and follow-up. We always include you in the entire process, because we truly believe in the healing power of families and that you know your child best.

Innovative Childhood Thrombocytosis Treatment at Nemours

Treating childhood thrombocytosis requires close monitoring and follow-up care, especially in the case of primary thrombocytosis (essential thrombocythemia). Secondary thrombocytosis often goes away when the underlying condition is appropriately treated. Primary pediatric thrombocytosis treatment depends on the symptoms, your child’s health and other factors, but typically includes medication therapy to suppress platelet production in the bone marrow.

For your child’s overall health and wellness, we also prescribe:
