Pediatric Philadelphia-positive B lymphoblastic leukemia with CD56 expression and L2 morphology: Case report and review of the literature
We present a unique case of pediatric B lymphoblastic leukemia with Philadelphia chromosome, CD56 expression, and predominantly L2 morphology. A review of the current literature demonstrates that this distinct combination of features is rare and may portend a worse prognosis, although there are too few cases to determine whether these features are prognostically independent of one another.
