Beschreibungen/Notizen

• Acute megakaryoblastic leukaemia (AML‐M7) is a rare myeloproliferative disorder in domestic animals. Recently, thanks to the greater availability of immunophenotype techniques, precise diagnosis is more easily made. The morphological evaluation has its limitations, especially in the study of poorly differentiated cells. Few reports have described AML‐M7 in dogs using flow cytometry. This clinical case points out the utility of flow cytometry in the characterization of AML‐M7 in a 3‐year‐old German Shepherd dog. Flow cytometry investigation has established megakaryocytic lineage involvement by showing the presence of two megakaryocyte/platelet associated antigens (CD9 and CD61). In human medicine CD9 may be used as a platelet and megakaryocyte marker. There is an evidence of cross‐reactivity of human anti‐CD9 monoclonal antibody with canine samples. To our knowledge, the use of CD9 has never been described before, for this purpose in the dog.
