Secondary Thrombocytosis Clinical Presentation
- Author: Koyamangalath Krishnan, MD, FRCP, FACP; Chief Editor: Emmanuel C Besa, MD more...
History
No unique symptoms are suggestive of secondary thrombocytosis (reactive thrombocytosis).
- Most patients are asymptomatic and are identified on routine blood counts.
- Patients may have symptoms that are referable to the primary condition that may have precipitated the secondary thrombocytosis (reactive thrombocytosis).
Physical
No distinguishing features of secondary thrombocytosis (reactive thrombocytosis) are found on physical examination.
- Physical findings reflect the underlying condition.
- In patients who have postsplenectomy thrombocytosis, evidence for a previous splenectomy should be evident on physical examination.[12]
Causes
Etiologic conditions associated with secondary thrombocytosis (reactive thrombocytosis) include the following:
- Infection and inflammatory disorders
- Postsplenectomy or hyposplenism
- Malignancy
- Trauma
- Chronic inflammatory conditions
- Hemorrhage, blood loss, or both
- Iron-deficiency anemia
- Rebound thrombocytosis
- Asplenia (anatomic or functional)
- Idiopathic
