Polycythemia Vera Transforming to Pure Erythroid Leukemia: A Diagnostic Mimic of Thrombotic Microangiopathy With High‐Risk TP53 Biology
Leukemic transformation of polycythemia vera (PV) to acute myeloid leukemia (AML) with a predominantly erythroid blast population is rare and carries a poor prognosis, particularly when driven by a TP53 mutation. We report a 55‐year‐old man with JAK2 V617F‐positive PV, previously noted on surveillance biopsy to harbor...
