No unique symptoms are suggestive of secondary thrombocytosis (reactive thrombocytosis). Most patients are asymptomatic and are identified on routine laboratory evaluation. Patients may have symptoms related to the primary condition that may have precipitated the thrombocytosis.

Thrombotic, vascular, and bleeding complications are rare in secondary thrombocytosis; they are more suggestive of a clonal thrombocytosis. [10]


Physical Examination

No distinguishing features of secondary thrombocytosis (reactive thrombocytosis) are found on physical examination. Physical examination findings reflect the underlying condition. In patients who have postsplenectomy thrombocytosis, evidence of a previous splenectomy should be apparent on physical examination. [14]
