I just had a colposcopy done to follow up on an ASCUS pap with high risk HPV. While morphologic assessment of blood smears, bone marrow smears, and tissue sections remains the cornerstone of lymphoma and leukemia diagnosis and classification, immunophenotyping is a very valuable and important complementary tool. Diverse immunophenotypic abnormalities were seen in patients with aHLH; the type of aberrant phenotype had no relationship to either clinical or laboratory findings, underlying/predisposing factors or to the response to treatment. Immunophenotypic analysis is an established tool in the diagnosis and classification of many hematolymphoid disorders; however, the role of flow cytometry (FC) in detecting bone marrow involvement during the staging of non-Hodgkin lymphoma (NHL) has yet to be defined.
