Trisomy 10 as the sole abnormality in biphenotypic leukemia.
We observed a case of acute biphenotypic leukemia with trisomy 10 as the sole abnormality. The patient was an adult male diagnosed with ALL(L2), Cell marker studies showed positivity for CD3, CD7, CD13 and CD33, so the phenotypic diagnosis was determined to be biphenotypic leukemia. No case of biphenotypic leukemia with trisomy 10 has been previously reported, until now.
