PathWays Case Study: Aug. 9

A 57-year-old woman was diagnosed with acute promyelocytic leukemia (APL) involving 40% of her bone marrow confirmed by PML-RARA quantitative PCR. She was started on induction therapy but developed treatment-related long QTc syndrome. Her regimen was reduced, and soon after, a follow-up bone marrow biopsy was performed. The bone marrow aspirate showed no morphologic features of residual acute leukemia but did reveal markedly bizarre erythroid atypia not seen in her earlier bone marrow specimen (see images).

We had case of APL some time ago. This is the reason that I remembered.

I have reviewed the APL case with cytopathology students last grand round CME.
I will share with them this case. I find these cases are very good.

VERY INFORMATIVE, I LEARN SOMETHING NEW
