BACKGROUND:

The coexistence of myeloproliferative neoplasms during pregnancy may lead to maternal and fetal complications, and early detection is essential.

CLINICAL CASE:

A 30-year-old primigravida. Prenatal examination revealed a significant increase in platelets and leukocytes. After exclusion of an infectious process and consultation with the haematologist, she was prescribed an antiplatelet agent. The pregnancy proceeded without thrombotic or haemorrhagic complications and was terminated by caesarean section at 40 weeks, indicated for lack of progress in labour. Specific treatment of the disease and follow-up were then initiated.

METHODOLOGY:

Articles published in the last 20 years were searched in PubMed and Clinical Key databases using MeSH "essential thrombocythemia AND pregnancy", "haematological neoplasms AND pregnancy".

RESULTS:

We obtained 14 articles, of which 3 were excluded because they did not include pregnant women. The final review consisted of 11 articles.

CONCLUSIONS:

Correct follow-up of antenatal care can warn of medical complications independent of pregnancy. In this case, timely intervention and involvement of other specialists is possible to confirm the diagnosis and make the best joint decision for the benefit of the mother and her unborn child.
