We report a case of BPDCN showing strong expression of E-cadherin, arising in a patient with history of primary myelofibrosis. Four more cases of BPDCN tested all showed strong expression of E-cadherin. Lack of awareness of this pattern of expression may lead to erroneous diagnosis of acute erythroid leukemia. It is increasingly becoming important to correctly identify this group of neoplasms, as approved new anti-CD123\u2013targeted therapies are becoming available.<\/jats:p>","DOI":"10.1177\/1066896920938130","type":"journal-article","created":{"date-parts":[[2020,7,1]],"date-time":"2020-07-01T07:09:25Z","timestamp":1593587365000},"page":"289-293","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["E-Cadherin
