Atypical cells can change back to normal cells if the underlying cause is removed or resolved. Rereview of PB smears from these patients, who had typical cutaneous findings of MF, did not identify definitive Sezary cells. Additionally, specific patterns of antigens are present on abnormal cells seen in leukemias and lymphomas. In these cases, LSC analysis is a methodology of choice because of its low sample requirements. It may be because the markers of interest are not available for flow cytometryor because fresh cells or tissue are not available (a requirement for flow cytometry immunophenotyping). The results from your immunophenotyping are compared to the pattern of antigens for normal cells as well as to patterns that are associated with abnormal cells (e.g., cells present with leukemias and lymphomas).
