Excerpt
Pure erythroid leukemia (PEL) is an uncommon subtype of acute myeloid leukemia (AML) [
7,
8,
13,
15]. While AML is recognized as a complication of polycythemia vera (PV) [
10‐
12], there are few reports of PV transformation to PEL [
1‐
4,
6,
8,
9]. Five reported cases of PEL arising from PV, diagnosed between 1956 and 1962, followed therapy with radioactive phosphorus (
32P) [

6,
9]. There were two case reports of transformation following therapy with hydroxyurea, in 1998 and 2012 [
2,
3]. More recently, transformation to PEL and erythroid sarcoma in patients with long-standing PV treated with phlebotomy and hydroxyurea was described [
5]. Here, we report molecular evidence of an unusual case of PEL with osseous involvement arising in a patient with known
JAK2 V617F-positive PV. …
