Cytomorphology of normal, reactive, dysmorphic, and dysplastic megakaryocytes in bone marrow aspirates

Gina Zini et al. Int J Lab Hematol. 2021 Jul.

Abstract

This paper aims to emphasize the importance of applying international consensus guidelines to detect qualitative and quantitative abnormalities of megakaryocytes on smears of bone marrow aspirates (BMA) for a shared and harmonized diagnostic path between different laboratories. Careful evaluation of megakaryocytes on BMA smears represents a cornerstone in the diagnosis of most clonal and nonclonal hematological diseases. Images associated with the detailed morphologic description of normal, reactive, abnormal, and dysplastic megakaryocytes are also reported together with examples of similar cells that, if not promptly identified, can lead to a morphological misdiagnosis.

Keywords: WHO Classification; bone marrow; megakaryocyte; morphology; myelodysplasia; myeloproliferative neoplasms.
