Abstract

Azurophilic granulation of blasts is a feature of acute myeloid leukemia (AML). Granular acute lymphoblastic leukemia (ALL) may mimic AML due to the presence of cytoplasmic granules in lymphoblasts, but cytochemistry and immunophenotyp- ing are helpful in making the correct diagnosis. Toluidine blue (TB) is a metachromatic dye, which stains basophils and myeloid blasts that exhibit basophilic differentiation. Reactivity for TB has not been described in lymphoblasts. We herein report two cases of granular ALL with blasts exhibiting reactivity for TB that caused diagnostic dilemma. Immunophenotyping and cytogenetic studies were helpful in making a correct diagnosis. This report of two rare case highlight the reactivity of lymphoblasts with TB not hitherto described and the importance of a detailed diagnostic work-up in acute leukemia.

Özet

BlastlarIn azurofilik granülasyonu, akut miyeloid löseminin (AML) bir özelliğidir. Granüler akut lenfoblastik lösemi (ALL), sitoplazmik granüllerin lenfoblastlardaki varlIğIna bağlI olarak AML’ye benzeyebilir, ancak histokimya ve immünofenotipleme doğru tanInIn konulmasInda yardImcIdIr. Toluidin mavisi (TB) bir metakromatik boya olup, bazofilik diferansiyasyon serg- ileyen bazofiller ve miyeloid blastlarI boyar. TB'ye yönelik reaktivite, lenfoblastlarda tanImlanmamIştIr. Bu yayInda, tanI ikil- emine neden olan TB’ye yönelik reaktivite sergileyen blastlar ile granüler ALL’ye yönelik iki vaka rapor edilmektedir. ûmmünofenotipleme ve sitogenetik çalIşmalar, doğru tanInIn konulmasInI sağlamIştIr. Bu iki nadir vaka raporu ile şimdiye dek tanImlanmamIş TB’li lenfoblastlarIn reaktivitesinin ve akut lösemide ayrIntIlI tanIsal tetkikin öneminin altI çizilmektedir.
