Herein we report 5 cases of MPO+, otherwise typical acute lymphoblastic leukemia (ALL) without the expression of other myeloid markers. In most cases, MPO positivity was detected in more than 20% of blasts by immunologic (flow cytometric) and enzymatic testing. The striking feature of most of these cases is a morphologic picture reminiscent of that seen in Burkitt-like B-cell ALL with basophilic cytoplasm and vacuoles but no expression of surface immunoglobulin. All cases responded to ALL therapy and should be distinguished from myeloid leukemia and from Burkitt leukemia\/lymphoma.<\/jats:p>","DOI":"10.1309\/ajcpz7e9imxvsnpt","type":"journal-article","created":{"date-parts":[[2009,7,15]],"date-time":"2009-07-15T21:43:54Z","timestamp":1247694234000},"page":"182-185","source":"Crossref","is-referenced-by-count":23,"title":["Acute
