Abstract:
It has been reported that malignancies of natural killer (NK) cell precursors, which are present in both myeloid and lymphoid antigens, are characterized by immature lymphoblastoid morphology with CD7+, CD33+ and CD56+ phenotype. Here, we report a 18-year-old man who was diagnosed with CD33- and CD13- NK cell precursor acute leukemia at first diagnosis. Following a 3-year remission state, he had a relapse as a testicular tumor and CD33+ myeloid/NK cell precursor acute leukemia after allogenic BMT. This case suggests that myeloid antigens are not necessary for diagnosis of myeloid/NK cell precursor acute leukemia.
