Second, unusual expression of surface antigens in ANKL cells was a prominent feature. For bone marrow testing, if cytogenetic tests are desired along with this test request, an additional specimen should be submitted. Clinical features, laboratory findings, morphologic, cytogenetic features, and Epstein-Barr virus status were important factors for diagnosing aggressive NK cell leukemia. ( 19952014). Diagnostic hematopathology has become an increasingly complex subspecialty, particularly with neoplastic disorders of blood and bone marrow. A pathologist, often one specializing in the study of blood diseases and/or blood cell cancers (a hematopathologist), will consider the results from the complete blood count (CBC), differential, blood smear, bone marrow findings, and flow cytometry immunophenotyping as well as other tests in order to provide a diagnostic interpretation.

Trisomy 12 is the second most frequent aberration detected by fluorescence in situ hybridization at the time of diagnosis (10-25%), and it confers an intermediate prognostic risk, with a median time to . The prognostic value of immunophenotyping in AML is controversial [ 3]. In agreement with previous studies, no immunophenotypic features (other than monocytic differentiation) predicted the presence of an 11q23 rearrangement. The dysplastic features are not unique for AML-MRC, but can be also detected in other hematopoietic diseases, such as MDS (Wu et al., 2013). Usually, 1 to 1.5 mL of spinal fluid is sufficient. Leukemia Acute Lymphocytic (Adults). An absolute CD8+ lymphocytosis correlates with disease progression and low expression of CD4 and CD8 (as found in autoimmune disease) The study was aimed to investigate the immunophenotypic and cytogenetic features of chronic lymphocytic leukemia (CLL) in order to provide an evidence for diagnosis and therapy.
