Diagnostic Considerations

In addition to acute immune thrombocytic purpura, the differential diagnosis for thrombocytopenia associated with large platelets (elevated mean platelet volume) includes Bernard-Soulier syndrome, Montreal platelet syndrome, gray-platelet syndrome, and Alport syndrome.

The differential diagnosis for thrombocytopenia due to ineffective thrombopoiesis includes Bernard-Soulier syndrome, Wiskott-Aldrich syndrome, Greaves syndrome, thrombopoietin deficiency, and megaloblastic anemia.

The differential diagnosis for leukocytic inclusions, sometimes called Döhle bodies, includes septicemia, myeloproliferative disorders, and pregnancy.

Blood smear (original magnification ×2000) in patient with May-Hegglin anomaly (MHA) demonstrates characteristic giant platelet with poorly defined granulation. Normal-sized platelet is also present. Trilobed neutrophil contains large, well-defined, basophilic, peripherally placed cytoplasmic inclusion body (resembling Döhle body). Image used with permission from Little, Brown.
