Hemangioma thrombocytopenia syndrome is a rare disorder characterized by a decrease in platelet count in combination with the presence of hemangiomas, benign vascular tumors. Hemangiomas can be located both on the skin and in deep tissues, including internal organs. This condition can lead to thrombocytopenia due to mechanical effects associated with hemangiomas, and can also develop against the background of various diseases, such as leukemia or autoimmune pathologies. The syndrome can manifest itself with varying degrees of severity and requires a comprehensive approach to diagnosis and treatment.
History of the disease and interesting historical facts
Hemangioma thrombocytopenia syndrome was first described in the early 20th century. The first observation of the relationship between hemangiomas and thrombocytopenia was published in the medical literature in the 1930s. Over the next decades, physicians began to record cases of the disease, which made it possible to identify it as a separate nosological entity. An important step in understanding the syndrome was the study of various mechanisms responsible for thrombocytopenia, including mechanical and immune ones.
Epidemiology
According to statistics, thrombocytopenia hemangioma syndrome occurs with a frequency of 1 in 50,000 newborns. The disease is most often diagnosed in young children, especially newborns and infants. Studies show that the disease occurs in girls almost twice as often as in boys. In recent years, there has been an increase in the number of cases of the syndrome, which is possibly due to more thorough and early diagnosis.
Genetic predisposition to this disease
There is evidence of a genetic predisposition to hemangioma thrombocytopenia syndrome. In some cases, mutations in genes involved in the regulation of vascular homeostasis and hematopoiesis have been identified. In particular, the VEGFA and ANGPT1 genes are involved in angiogenesis and may play an important role in the development of hemangiomas and associated thrombocytopathies. However, the exact mechanisms and other genes involved require further study.
Risk factors for the development of this disease
Risk factors that contribute to the development of hemangioma thrombocytopenia syndrome include:
- Genetic predisposition.
- Premorbid conditions indicating hemostasis disorders.
- Contact with chemicals during pregnancy.
- Infections during pregnancy, such as rubella or cytomegalovirus infection.
- Maternal age: The risk increases in women over 35 years of age.
Diagnosis of this disease
The main symptoms of hemangioma thrombocytopenia syndrome may include:
- Enlargement of the hemangioma, sometimes with pronounced hyperemia.
- Symptoms of thrombocytopenia include bruising, frequent nosebleeds, bleeding gums.
- General signs of anemia include fatigue and pale skin.
The following are used for diagnostics:
- Laboratory blood tests for platelet levels and coagulograms.
- Radiological tests such as ultrasound to determine the size of the hemangioma.
- MRI or CT scan may be ordered to assess the extent of hemangiomas.
- Differential diagnosis includes exclusion of other causes of thrombocytopenia, such as autoimmune diseases or leukemia.
Treatment
General treatment for hemangioma thrombocytopenia syndrome may include:
- Monitor the patient if the hemangioma is small and does not cause serious complications.
- Pharmacological treatment: corticosteroids to reduce the size of the hemangioma and increase platelet levels.
- Surgical removal of hemangioma in case of serious complications or large tumor sizes.
- Sclerotherapy to reduce the hemangioma if surgery is not possible.
List of medications used to treat this disease
- Dexafort (dexamethasone).
- Prednisolone.
- Chemotherapy drugs in difficult cases (eg, vincristine).
- Beta blockers such as propranolol for the treatment of hemangiomas in children.
Disease monitoring
Control steps for monitoring hemangioma thrombocytopenia syndrome include:
- Regular blood tests for platelet levels every 2-3 months.
- Ultrasound examinations to assess the dynamics of hemangioma.
- Evaluation of possible complications such as thrombocytopenic purpura.
The prognosis is usually good with early diagnosis and adequate treatment. Possible complications may include extensive bleeding and the need for blood transfusions.
Age-related features of the disease
Thrombocytopenia hemangioma syndrome may present differently in different age groups:
- In newborns, hemangiomas most often have a benign course, many of them regress without intervention.
- In older children, the syndrome may present with more pronounced symptoms of thrombocytopenia.
- In adulthood, there is a high risk of complications requiring more aggressive treatment.

Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov recommends:
- Get regular check-ups, especially if you have risk factors.
- Contact specialists promptly if any alarming symptoms occur.
- Discuss all possible treatment options and possible side effects of medications with your doctor.
- Include foods rich in vitamins and minerals in your diet to maintain normal platelet levels.
