Flow cytometry:ALAL-NOS
From haematologyetc.co.uk
Reserved for cases where a primitive haematopoietic malignancy is established but where confident assignment to any specific category is not possible.
This diagnosis is rarely indcated as a final classification since almost all cases can be ascribed to an existing group. However, as a provisional diagnosis the term can have some value in cases where additional immunohistochemistry or molecular test results are awaited that might provide further diagnostic certainty.
