73 participants received microscopical slides of this case of AML M0. | The case is characterized by 30% "cytic" cells which proved to be mature T-lymphocytes by immunology. | The blastic nature of the remaining mononuclear cells was recognized by 55 participants. |

|
In rather thick areas the blastic nature was difficult to see. | I would count three blasts and one lymphocyte | Clearly a blast not compatible with CLL. |
 |  |  |
|
The cells look lymphatic however immunology clarifies the myeloid nature. | More blasts and one "I dont know cell". | A giant platelet and a blast. |
 |  |  |
|
The CD3 positive cells are mature T-lymphocytes whereas the leukemic cells are those showing weak CD4 expression. | | The cells are positive for CD34 and CD13 |

CD13 and HLA-DR | | |
