Now, if an adult has a small number of mature B cells but also has a large number of immature B cells which are positive for CD19 (remember, CD19 is a B-cell marker) and also positive for both CD34 and CD20 (which identifies those cells are both immature and abnormal), then the personhasan immature B-cell leukemia known as B-lymphoblastic leukemia. Among T-cell populations outside the thymus, phenotypes associated with malignancy included 1) loss of pan-T antigens (including loss of the beta chain of the T-cell antigen receptor), 2) coexpression or loss of T-subset antigens, 3) Leu-6+ T-lineage, and 4) MB-1+ T lineage. Leukemic myeloblasts expressed many leukocyte differentiation antigens, thus reflecting association with myeloid lineage and maturation level. Application of these criteria to a series of nearly 500 cases of lymphoma indicated that over 90% of B-lineage and about 80% of T-lineage neoplasms manifested immunophenotypic abnormalities that could distinguish them from benign, reactive lymphoid processes.

These abnormalities were related to immunophenotypic markers as This study prospectively analysed the relationships between immunophenotypic and cytogenetic features of blast cells in 432 acute non-lymphoblastic leukemias (ANLL) at presentation. However it is frequently misdiagnosed because of its non-specific imaging and histological pattern. The present results further confirm that IGH@ rearrangement is not a rare genomic abnormality in B-CLL, and also show both that t(14;19)(q32;q13.2) is the most common cytogenetic change involving IGH@ rearrangement detected by FISH in B-CLL and that IGH@ rearrangement is correlated with CD38 expression. low reading R03.1 .
