Thrombocytosis Differential Diagnosis

Differentiating the diseases that can cause thrombocytosis :

Category Condition Etiology Mechanism Inherited Acquried Clinical manifestations Para−clinical findings Gold standard Associated findings
Demography History Symptoms Signs
Lab Findings Imaging
Fever Rash Bleeding BP Splenomegaly Jaundice Other CBC PBS Bone marrow exam PT PTT UA
Decreased platelet production Platelet destruction in blood Platelet destruction in spleen Plt HB WBC
Autonomous thrombocytosis Hematologic malignancies Essential thrombocythemia
Polycythemia vera
Primary myelofibrosis
Chronic myeloid leukemia
Myelodysplastic syndromes[1]
