Morphologic and immunophenotypic evolution for this secondary AML case. Morphologic (A) (upper, primary diagnosis; upper middle, 1st relapse; lower middle, 2nd relapse; and lower, post anti-CLL1 CAR T-cell therapy) and flow cytometric (B,C) features at primary diagnosis (upper panel), 1st relapse (upper middle panel), 2nd relapse (lower middle panel), and post anti-CLL1 CAR T-cell therapy (lower panel) in this secondary AML case; gating: all events (All Events) or blast and erythroid cells (Blast+E). The green, blue, orange, light blue, gray and red dots represent lymphocytes, monocytes, neutrophils, erythrocytes, debris, and blasts population, respectively.
