Abstractor Notes
(This code is effective for cases diagnosed 2010 and later. For cases diagnosed prior to 2010 see code 9801/3.) Although this leukemia meets the criteria for assignment to both T and myeloid lineage, the blasts lack the genetic abnormalities. This is a rare leukemia accounting for less than 1% of leukemias. It is relatively more frequent in children but is seen in both children and adults. There are no unique clinical features for this leukemia.
