CSF cytology was negative for malignant cells. -, Blood. Application of immunophenotypic analysis in distinguishing chronic myelomonocytic leukemia from reactive monocytosis. This case suggested that chromosomal alterations may precede morphological, flow cytometric and clinical changes and accelerate progression of the disease. More practically, and although the relationships demonstrated only represent a fraction of homogeneous immunophenotypic subgroups, identification of such immunophenotypic features should prompt careful karyotypic examination, eventually using molecular biology analysis on non-growing cells. It can be used for identifying the lineage of the cell in smears of tissues with suspected lymphoma or histocytic sarcoma. Most of the antigens that flow cytometry immunophenotyping detects are identified by a CD (clusters of differentiation or cluster designation) number. These plasma cells are negative for CD19.

Anaplastic lymphoma kinase protein was detected in about 33% (3/9) of ALCLs examined by flow cytometric immunophenotyping (FCI); expression was validated by immunohistochemical analysis. Pagana, K.
